* Adds a bit of package documentation.
* Returns an empty response from restore to avoid EOF errors.
* Adds API client support for snapshots.
* Makes internal file names match on-disk file snapshots.
* Adds DC and token coverage for snapshot API test.
* Adds missing documentation.
* Adds a unit test for the snapshot client endpoint.
* Moves the connection pool out of the client for easier testing.

This is independent of Consul so we can pull this out into a library
later if we want to.
* Cleans up snapshot and archive and completes archive tests.
* Sends a clear error for snapshot operations in dev mode.
Snapshots require the Raft snapshots to be readable, which isn't supported

This gives folks a way to extract data even if the cluster has no

* Don't reuse the same agent config in TestAgent_ReconnectConfigSettings
When DNS prepared query fails over to another datacenter and the datacenter
returns some nodes, the DNS result does not translate WAN addresses even when
translation is enabled for SRV and A queries, and returns the wrong datacenter
(the one that failed over) for SRV queries.
