We can't actually return a fine-grained index from these tables unless

Adds support for snapshots and restores. ( #2396 )
...
* Updates Raft library to get new snapshot/restore API.
* Basic backup and restore working, but need some cleanup.
* Breaks out a snapshot module and adds a SHA256 integrity check.
* Adds snapshot ACL and fills in some missing comments.
* Require a consistent read for snapshots.
* Make sure snapshot works if ACLs aren't enabled.
* 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.
* Fixes an incidental issue in the prepared query unit test.
I realized I had two servers in bootstrap mode so this wasn't a good setup.
* Adds a half close to the TCP stream and fixes panic on error.
* Adds client and endpoint tests for snapshots.
* Moves the pool back into the snapshot RPC client.
* Adds a TLS test and fixes half-closes for TLS connections.
* Tweaks some comments.
* Adds a low-level snapshot test.
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
in dev mode. Send a clear error instead of a deep-down Raft one.
* Adds docs for the snapshot endpoint.
* Adds a stale mode and index feedback for snapshot saves.
This gives folks a way to extract data even if the cluster has no
leader.
* Changes the internal format of a snapshot from zip to tgz.
* Pulls in Raft fix to cancel inflight before a restore.
* Pulls in new Raft restore interface.
* Adds metadata to snapshot saves and a verify function.
* Adds basic save and restore snapshot CLI commands.
* Gets rid of tarball extensions and adds restore message.
* Fixes an incidental bad link in the KV docs.
* Adds documentation for the snapshot CLI commands.
* Scuttle any request body when a snapshot is saved.
* Fixes archive unit test error message check.
* Allows for nil output writers in snapshot RPC handlers.
* Renames hash list Decode to DecodeAndVerify.
* Closes the client connection for snapshot ops.
* Lowers timeout for restore ops.
* Updates Raft vendor to get new Restore signature and integrates with Consul.
* Bounces the leader's internal state when we do a restore.

Rather than scale this we just bump it up a bit. It'll be on the edge in
the lower-performance default mode, and will have plenty of margin in the
high-performance mode. This seems like a reasonable compromise to keep the
logic here simple vs. scaling, and seems inline with the expectations of
the different modes of operation.

Chase casting types.CheckID to a string into the state_store.
...
It turns out the indexer can only use strings as arguments when
creating a query. Cast `types.CheckID` to a `string` before calling
into `memdb`.
Ideally the indexer would be smart enough to do this at compile-time,
but I need to look into how to do this without reflection and the
runtime package. For the time being statically cast `types.CheckID`
to a `string` at the call sites.

Float a type balloon. Some strings are square pegs in round holes.
...
This experiment was brought about because of variable naming
confusion where name and checkIDs were interchanged. Gave CheckID
an Qualified Type Name and chased downstream changes.

Refactors TxnRequest/TxnResponse into a form that will allow non-KV ops.

This isn't needed/used yet, but it's a good hook to get in there so we
can add more atomic operations in the future. The Go API hides this detail
so that feels like a KV-specific API. The implications on the REST API are
pretty minimal.

Now that there is no longer an event loop driven directly by Serf, start the ServerManager task after Serf has been setup.
