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

csi: prevent in-use plugin GC from blocking volume GC (#9141)
During CSI plugin GC, we don't return an error if the volume is in use,
because this is not an error condition. If we were to return an error during a
`nomad system gc`, we would not continue on to GC volumes.

But check for the specific error message fails if the GC is performed on a
worker rather than on the leader, due to RPC forwarding wrapping the error
message. Use a less specific test so that we don't return an error.

Implement 'batch mode' for persisting allocations on the client. (#9093)
Fixes #9047, see problem details there.

As a solution, we use BoltDB's 'Batch' mode that combines multiple
parallel writes into small number of transactions. See
https://github.com/boltdb/bolt#batch-read-write-transactions for
more information.

Enforce bounds on MaxQueryTime (#9064)
The MaxQueryTime value used in QueryOptions.HasTimedOut() can be set to
an invalid value that would throw off how RPC requests are retried.

This fix uses the same logic that enforces the MaxQueryTime bounds in the
blockingRPC() call.

Michael Schurter 8ccbd92cb6 api: add field filters to /v1/{allocations,nodes}
Fixes #9017

The ?resources=true query parameter includes resources in the object
stub listings. Specifically:

- For `/v1/nodes?resources=true` both the `NodeResources` and
  `ReservedResources` field are included.
- For `/v1/allocations?resources=true` the `AllocatedResources` field is
  included.

The ?task_states=false query parameter removes TaskStates from
/v1/allocations responses. (By default TaskStates are included.)

Event Stream API/RPC (#8947)
This Commit adds an /v1/events/stream endpoint to stream events from.

The stream framer has been updated to include a SendFull method which
does not fragment the data between multiple frames. This essentially
treats the stream framer as a envelope to adhere to the stream framer
interface in the UI.

If the `encode` query parameter is omitted events will be streamed as
newline delimted JSON.

Seth Hoenig ed13e5723f consul/connect: dynamically select envoy sidecar at runtime
As newer versions of Consul are released, the minimum version of Envoy
it supports as a sidecar proxy also gets bumped. Starting with the upcoming
Consul v1.9.X series, Envoy v1.11.X will no longer be supported. Current
versions of Nomad hardcode a version of Envoy v1.11.2 to be used as the
default implementation of Connect sidecar proxy.

This PR introduces a change such that each Nomad Client will query its
local Consul for a list of Envoy proxies that it supports (https://github.com/hashicorp/consul/pull/8545)
and then launch the Connect sidecar proxy task using the latest supported version
of Envoy. If the `SupportedProxies` API component is not available from
Consul, Nomad will fallback to the old version of Envoy supported by old
versions of Consul.

Setting the meta configuration option `meta.connect.sidecar_image` or
setting the `connect.sidecar_task` stanza will take precedence as is
the current behavior for sidecar proxies.

Setting the meta configuration option `meta.connect.gateway_image`
will take precedence as is the current behavior for connect gateways.

`meta.connect.sidecar_image` and `meta.connect.gateway_image` may make
use of the special `${NOMAD_envoy_version}` variable interpolation, which
resolves to the newest version of Envoy supported by the Consul agent.

Tim Gross 9b4917ae5f csi: volumewatcher only needs one pass to collect past claims
If a volume GC and a `nomad volume detach` command land concurrently, we can
end up with multiple claims without an allocation, which results in extra

csi: validate mount options during volume registration (#9044)
Volumes using attachment mode `file-system` use the CSI filesystem API when
they're mounted, and can be passed mount options. But `block-device` mode
volumes don't have this option. When RPCs are made to plugins, we are silently
dropping the mount options we don't expect to see, but this results in a poor
operator experience when the mount options aren't honored. This changeset
makes passing mount options to a `block-device` volume a validation error.

csi: allow more than 1 writer claim for multi-writer mode (#9040)
Fixes a bug where CSI volumes with the `MULTI_NODE_MULTI_WRITER` access mode
were using the same logic as `MULTI_NODE_SINGLE_WRITER` to determine whether
the volume had writer claims available for scheduling.

Extends CSI claim endpoint test to exercise multi-reader and make sure `WriteFreeClaims`
is exercised for multi-writer in feasibility test.

Seth Hoenig f44a4f68ee consul/connect: trigger update as necessary on connect changes
This PR fixes a long standing bug where submitting jobs with changes
to connect services would not trigger updates as expected. Previously,
service blocks were not considered as sources of destructive updates
since they could be synced with consul non-destructively. With Connect,
task group services that have changes to their connect block or to
the service port should be destructive, since the network plumbing of
the alloc is going to need updating.

Fixes #8596 #7991

Michael Schurter 765473e8b0 jobspec: lower min cpu resources from 10->1
Since CPU resources are usually a soft limit it is desirable to allow
setting it as low as possible to allow tasks to run only in "idle" time.

Setting it to 0 is still not allowed to avoid potential unintentional
side effects with allowing a zero value. While there may not be any side
effects this commit attempts to minimize risk by avoiding the issue.

This does *not* change the defaults.

Seth Hoenig af9543c997 consul: fix validation of task in group-level script-checks
When defining a script-check in a group-level service, Nomad needs to
know which task is associated with the check so that it can use the
correct task driver to execute the check.

This PR fixes two bugs:
1) validate service.task or service.check.task is configured
2) make service.check.task inherit service.task if it is itself unset

RPC Timeout/Retries account for blocking requests (#8921)
The current implementation measures RPC request timeout only against
config.RPCHoldTimeout, which is fine for non-blocking requests but will
almost surely be exceeded by long-poll requests that block for minutes
at a time.

This adds an HasTimedOut method on the RPCInfo interface that takes into
account whether the request is blocking, its maximum wait time, and the
RPCHoldTimeout.
