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.

It includes the work over the state store, the PRC server, the HTTP server, the go API package and the CLI's command. To read more on the actuall functionality, refer to the RFCs [NMD-178] Locking with Nomad Variables and [NMD-179] Leader election using locking mechanism for the Autoscaler.
