* Move CLI to TransportSqlAction
* Moves REST endpoint from `/_cli` to `/_sql/cli`
* Removes the special purpose CLI transport action instead
implements the CLI entirely on the REST layer, delegating
all SQL stuff to the same action that backs the `/_sql` REST
API.
* Reworks "embedded testing mode" to use a `FilterClient` to
bounce capture the sql transport action and execute in embedded.
* Switches CLI formatting from consuming the entire response
to consuming just the first page of the response and returning
a `cursor` that can be used to read the next page. That read is
not yet implemented.
* Switch CLI formatting from the consuming the `RowSetCursor` to
consuming the `SqlResponse` object.
* Adds tests for CLI formatting.
* Support next page in the cli
* Rename cli's CommandRequest/CommandResponse to
QueryInitRequest/QueryInitResponse to line up with jdbc
* Implement QueryPageRequest/QueryPageResponse in cli
* Use `byte[]` to represent the cursor in the cli. Those bytes
mean something, but only to the server. The only reasonint that
the client does about them is "if length == 0 then there isn't a
next page."
* Pull common code from jdbc's QueryInitRequest, QueryPageRequest,
QueryInitResponse, and QueryPageResponse into the shared-proto
project
* By implication this switches jdbc's QueryPageRequest to using
the same cursor implementation as the cli

Too big. Sorry. Some good things though:
1. Share some code between CLI and JDBC. Probably a good thing
at this point, better as we go on, I think.
2. Add round trip tests for all of proto.
3. Remove the `data` member from `QueryInitResponse` and
`QueryPageResponse` so we response serialization is consistent with
everything else.
Original commit: elastic/x-pack-elasticsearch@c6940a32ed
* Move read from a static method to a ctor to mirror core.
* Make read and writes read and write the same data.
* Instead of the "header" integer use a byte for the response
type.
* For responses that do not make their request type obvious
then serialize the request type.
* Remove the request type member from requests and responses and
replace with an abstract method. These type members have caused
us trouble in core in the past.
* Remove the Message superclass as it didn't have anything in it.
* Pass client version to the request reader and response writer.
* Add round trip tests for the protocol.
* Force Requests and Responses to provide good `toString`, `equals`,
and `hashCode`.
Original commit: elastic/x-pack-elasticsearch@653ed8c27f
* Switch `data` member from Object to `String`
* Compress packages on server so easier to build `data` as `String`
* Move write of `data` member into `encode` method
* Move read of `data` member into ctor
Original commit: elastic/x-pack-elasticsearch@e3a52e7493
* A unit test for cli
* Licenses for cli
* Remove licenses for protos (no more deps)
* `SHOW TABLES` returns results in order (makes testing easier)
* Clean up embedded jdbc server
* Wire up embedded cli server
