The RPC handlers expect to see `nil` ACL objects whenever ACLs are disabled. By
using `nil` as a sentinel value, we have the risk of nil pointer exceptions and
improper handling of `nil` when returned from our various auth methods that can
lead to privilege escalation bugs. This is the third in a series to eliminate
the use of `nil` ACLs as a sentinel value for when ACLs are disabled.
This patch involves creating a new "virtual" ACL object for checking permissions
on client operations and a matching `AuthenticateClientOnly` method for
client-only RPCs that can produce that ACL.
Unlike the server ACLs PR, this also includes a special case for "legacy" client
RPCs where the client was not previously sending the secret as it
should (leaning on mTLS only). Those client RPCs were fixed in Nomad 1.6.0, but
it'll take a while before we can guarantee they'll be present during upgrades.

This PR solves a defect in the deserialization of api.Port structs when returning structs from theEventStream.
Previously, the api.Port struct's fields were decorated with both mapstructure and hcl tags to support the network.port stanza's use of the keyword static when posting a static port value. This works fine when posting a job and when retrieving any struct that has an embedded api.Port instance as long as the value is deserialized using JSON decoding. The EventStream, however, uses mapstructure to decode event payloads in the api package. mapstructure expects an underlying field named static which does not exist. The result was that the Port.Value field would always be set to 0.
Upon further inspection, a few things became apparent.
The struct already has hcl tags that support the indirection during job submission.
Serialization/deserialization with both the json and hcl packages produce the desired result.
The use of of the mapstructure tags provided no value as the Port struct contains only fields with primitive types.
This PR:
Removes the mapstructure tags from the api.Port structs
Updates the job parsing logic to use hcl instead of mapstructure when decoding Port instances.
Closes#11044

* Remove Managed Sinks from Nomad
Managed Sinks were a beta feature in Nomad 1.0-beta2. During the beta
period it was determined that this was not a scalable approach to
support community and third party sinks.

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.
