events: fix wildcard namespace handling (#10935)
This fixes a bug in the event stream API where it currently interprets
namespace=* as an actual namespace, not a wildcard. When Nomad parses
incoming requests, it sets namespace to default if not specified, which
means the request namespace will never be an empty string, which is what
the event subscription was checking for. This changes the conditional
logic to check for a wildcard namespace instead of an empty one.

It also updates some event tests to include the default namespace in the
subscription to match current behavior.

Fixes #10903

Event Stream: Track ACL changes, unsubscribe on invalidating changes (#9447)
* upsertaclpolicies

* delete acl policies msgtype

* upsert acl policies msgtype

* delete acl tokens msgtype

* acl bootstrap msgtype

wip unsubscribe on token delete

test that subscriptions are closed after an ACL token has been deleted

Start writing policyupdated test

* update test to use before/after policy

* add SubscribeWithACLCheck to run acl checks on subscribe

* update rpc endpoint to use broker acl check

* Add and use subscriptions.closeSubscriptionFunc

This fixes the issue of not being able to defer unlocking the mutex on
the event broker in the for loop.

handle acl policy updates

* rpc endpoint test for terminating acl change

* add comments

filter on additional filter keys, remove switch statement duplication
properly wire up durable event count

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.
