Seth Hoenig 238ac718f2 connect: use exp backoff when waiting on consul envoy bootstrap
This PR wraps the use of the consul envoy bootstrap command in
an expoenential backoff closure, configured to timeout after 60
seconds. This is an increase over the current behavior of making
3 attempts over 6 seconds.

Should help with #10451

Fixup uses of sanity (#10187)
* Fixup uses of `sanity`
* Remove unnecessary comments.

These checks are better explained by earlier comments about
the context of the test. Per @tgross, moved the tests together
to better reinforce the overall shared context.

* Update nomad/fsm_test.go

Fix some errcheck errors (#9811)
* Throw away result of multierror.Append

When given a *multierror.Error, it is mutated, therefore the return
value is not needed.

* Simplify MergeMultierrorWarnings, use StringBuilder

* Hash.Write() never returns an error

* Remove error that was always nil

* Remove error from Resources.Add signature

When this was originally written it could return an error, but that was
refactored away, and callers of it as of today never handle the error.

* Throw away results of io.Copy during Bridge

* Handle errors when computing node class in test

gatedwriter: Fix race condition (#9791)
If one thread calls `Flush()` on a gatedwriter while another thread attempts to
`Write()` new data to it, strange things will happen.

The test I wrote shows that at the very least you can write _while_ flushing,
and the call to `Write()` will happen during the internal writes of the
buffered data, which is maybe not what is expected. (i.e. the `Write()`'d data
will be inserted somewhere in the middle of the data being `Flush()'d`)

It's also the case that, because `Write()` only has a read lock, if you had
multiple threads trying to write ("read") at the same time you might have data
loss because the `w.buf` that was read would not necessarily be up-to-date by
the time `p2` was appended to it and it was re-assigned to `w.buf`. You can see
this if you run the new gatedwriter tests with `-race` against the old implementation:

```
WARNING: DATA RACE
Read at 0x00c0000c0420 by goroutine 11:
  runtime.growslice()
      /usr/lib/go/src/runtime/slice.go:125 +0x0

      /home/hicks/workspace/nomad/helper/gated-writer/writer_test.go:90 +0xea
```

This race condition is fixed in this change.

docker: introduce a new hcl2-friendly mount syntax (#9635)
Introduce a new more-block friendly syntax for specifying mounts with a new `mount` block type with the target as label:

```hcl
config {
  image = "..."

  mount {
    type = "..."
    target = "target-path"
    volume_options { ... }
  }
}
```

The main benefit here is that by `mount` being a block, it can nest blocks and avoids the compatibility problems noted in https://github.com/hashicorp/nomad/pull/9634/files#diff-2161d829655a3a36ba2d916023e4eec125b9bd22873493c1c2e5e3f7ba92c691R128-R155 .

The intention is for us to promote this `mount` blocks and quietly deprecate the `mounts` type, while still honoring to preserve compatibility as much as we could.

This addresses the issue in https://github.com/hashicorp/nomad/issues/9604 .

Seth Hoenig beaa6359d5 consul/connect: fix regression where client connect images ignored
Nomad v1.0.0 introduced a regression where the client configurations
for `connect.sidecar_image` and `connect.gateway_image` would be
ignored despite being set. This PR restores that functionality.

There was a missing layer of interpolation that needs to occur for
these parameters. Since Nomad 1.0 now supports dynamic envoy versioning
through the ${NOMAD_envoy_version} psuedo variable, we basically need
to first interpolate

  ${connect.sidecar_image} => envoyproxy/envoy:v${NOMAD_envoy_version}

then use Consul at runtime to resolve to a real image, e.g.

  envoyproxy/envoy:v${NOMAD_envoy_version} => envoyproxy/envoy:v1.16.0

Of course, if the version of Consul is too old to provide an envoy
version preference, we then need to know to fallback to the old
version of envoy that we used before.

  envoyproxy/envoy:v${NOMAD_envoy_version} => envoyproxy/envoy:v1.11.2@sha256:a7769160c9c1a55bb8d07a3b71ce5d64f72b1f665f10d81aa1581bc3cf850d09

Beyond that, we also need to continue to support jobs that set the
sidecar task themselves, e.g.

  sidecar_task { config { image: "custom/envoy" } }

which itself could include teh pseudo envoy version variable.

Seth Hoenig 9ec1af5310 command: remove use of flag impls from consul
In a few places Nomad was using flag implementations directly
from Consul, lending to Nomad's need to import consul. Replace
those uses with helpers already in Nomad, and copy over the bare
minimum needed to make the autopilot flags behave as they have.

Send events to EventSinks (#9171)
* Process to send events to configured sinks

This PR adds a SinkManager to a server which is responsible for managing
managed sinks. Managed sinks subscribe to the event broker and send
events to a sink writer (webhook). When changes to the eventstore are
made the sinkmanager and managed sink are responsible for reloading or
starting a new managed sink.

* periodically check in sink progress to raft

Save progress on the last successfully sent index to raft. This allows a
managed sink to resume close to where it left off in the event of a lost
server or leadership change

dereference eventsink so we can accurately use the watchch

When using a pointer to eventsink struct it was updated immediately and our reload logic would not trigger

artifact/template: make destination path absolute inside taskdir (#9149)
Prior to Nomad 0.12.5, you could use `${NOMAD_SECRETS_DIR}/mysecret.txt` as
the `artifact.destination` and `template.destination` because we would always
append the destination to the task working directory. In the recent security
patch we treated the `destination` absolute path as valid if it didn't escape
the working directory, but this breaks backwards compatibility and
interpolation of `destination` fields.

This changeset partially reverts the behavior so that we always append the
destination, but we also perform the escape check on that new destination
after interpolation so the security hole is closed.

Also, ConsulTemplate test should exercise interpolation

Tim Gross 6df36e4cdb artifact/template: prevent file sandbox escapes
Ensure that the client honors the client configuration for the
`template.disable_file_sandbox` field when validating the jobspec's
`template.source` parameter, and not just with consul-template's own `file`
function.

Prevent interpolated `template.source`, `template.destination`, and
`artifact.destination` fields from escaping file sandbox.

Fixes #9047, see problem details there.

As a solution, we use BoltDB's 'Batch' mode that combines multiple

Seth Hoenig 5b072029f2 consul/connect: add initial support for ingress gateways
This PR adds initial support for running Consul Connect Ingress Gateways (CIGs) in Nomad. These gateways are declared as part of a task group level service definition within the connect stanza.

```hcl
service {
  connect {
    gateway {
      proxy {
        // envoy proxy configuration
      }
      ingress {
        // ingress-gateway configuration entry
      }
    }
  }
}
```

A gateway can be run in `bridge` or `host` networking mode, with the caveat that host networking necessitates manually specifying the Envoy admin listener (which cannot be disabled) via the service port value.

Currently Envoy is the only supported gateway implementation in Consul, and Nomad only supports running Envoy as a gateway using the docker driver.

Aims to address #8294 and tangentially #8647

driver/docker: allow configurable pull context timeout setting.
Pulling large docker containers can take longer than the default
context timeout. Without a way to change this it is very hard for
users to utilise Nomad properly without hacky work arounds.

This change adds an optional pull_timeout config parameter which
gives operators the possibility to account for increase pull times
where needed. The infra docker image also has the option to set a
custom timeout to keep consistency.

RPC errors must be wrapped in order to wrap internal errors (#8632)
The CSI client RPC uses error wrapping to detect the type of error bubbling up
from plugins, but if the errors we get aren't wrapped at each layer, we can't
unwrap the inner error.

Also eliminates some unused args.
