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.

Save progress on the last successfully sent index to raft. This allows a

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.

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.

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.)

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.

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.

Stop coercing version of new job to 0 in the state_store, so that we can add

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
no-op work when finding claims to collect as past claims.
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.
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.
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
Non-destructive half in #7192
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.
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
Fixes#8952
Noticed this error in some production logs, and they were far from
helpful. Changes:
1. Include job ID in logs
2. Wrap errors and log once instead of double log lines
3. Test fsm error handling behavior
