* Upgrade from hashicorp/go-msgpack v1.1.5 to v2.1.0
Fixes#16808
* Update hashicorp/net-rpc-msgpackrpc to v2 to match go-msgpack
* deps: use go-msgpack v2.0.0
go-msgpack v2.1.0 includes some code changes that we will need to
investigate furthere to assess its impact on Nomad, so keeping this
dependency on v2.0.0 for now since it's no-op.

* command/agent/host: collect host data, multi platform
* nomad/structs/structs: new HostDataRequest/Response
* client/agent_endpoint: add RPC endpoint
* command/agent/agent_endpoint: add Host
* api/agent: add the Host endpoint
* nomad/client_agent_endpoint: add Agent Host with forwarding
* nomad/client_agent_endpoint: use findClientConn
This changes forwardMonitorClient and forwardProfileClient to use
findClientConn, which was cribbed from the common parts of those
funcs.
* command/debug: call agent hosts
* command/agent/host: eliminate calling external programs
Passes in agent enable_debug config to nomad server and client configs.
This allows for rpc endpoints to have more granular control if they
should be enabled or not in combination with ACLs.
enable debug on client test
Copy the updated version of freeport (sdk/freeport), and tweak it for use
in Nomad tests. This means staying below port 10000 to avoid conflicts with
the lib/freeport that is still transitively used by the old version of
consul that we vendor. Also provide implementations to find ephemeral ports
of macOS and Windows environments.
Ports acquired through freeport are supposed to be returned to freeport,
which this change now also introduces. Many tests are modified to include
calls to a cleanup function for Server objects.
This should help quite a bit with some flakey tests, but not all of them.
Our port problems will not go away completely until we upgrade our vendor
version of consul. With Go modules, we'll probably do a 'replace' to swap
out other copies of freeport with the one now in 'nomad/helper/freeport'.
