* SQL: Move shared REST client methods to shared-client
This commit is a preliminary step for moving JDBC to the REST client. It extracts the common REST clients from CLI and moves it to shared-client. This will allow us to move to the 5 project setup: rest-proto, shared-client, server, jdbc, cli with the following dependencies:
server <-- rest-proto
shared-client <-- rest-proto
jdbc <-- shared-client
cli <-- shared-client
Relates to elastic/x-pack-elasticsearch#3419

This teaches SQL to parse Elasticsearch's standard error responses
but doesn't change SQL to general Elasticsearch's standard error responses
in all cases. That can come in a followup. We do this parsing with
jackson-core, the same dependency Elasticsearch uses for parsing
json. We shade jackson-core in the JDBC driver so that users don't have to worry about
dependency clashes. We do not do so in the CLI because it is a standalone
application.
We get a few "bonus" changes along the way:
1. We save a copy operation. Before this change responses were spooled
into memory and then parsed. After this change they are parsed directly
from the response stream.
2. We had a few classes entirely to support the spooling operation that we
no longer need: `BytesArray`, `FastByteArrayInputStream`, and
`BasicByteArrayOutputStream`.
3. SQL's `Version` was incorrectly parsing the version from the jar manifest.
We didn't notice because the test was rigged to return `UNKNOWN` because
we *were* running the test from the compiled classes directory instead of the
jar. As part of shading jackson we moved running the tests to running against
the shaded jar. Now we can actually assert that we parse the version correctly.
It turns out we weren't. So I fixed it.

These wrap `DataInput` and `DataOutput` to add the protocol
version being serialized. This is similar to the mechanism
used by core and it has made adding and removing fields from
the serialization protocol fairly simple.

Builds on elastic/x-pack-elasticsearch#2403 to move all of sql's integration testing into
qa modules with different running server configurations. The
big advantage of this is that it allows us to test the cli and
jdbc with security present.
Creating a project that depends on both cli and jdbc and the
server has some prickly jar hell issues because cli and jdbc
package their dependencies in the jar. This works around it
in a few days:
1. Include only a single copy of the JDBC dependencies with
careful gradle work.
2. Do not include the CLI on the classpath at all and instead
run it externally.
I say "run it externally" rather than "fork it" because Elasticsearch
tests aren't allowed to fork other processes. This is forbidden
by seccomp on linux and seatbelt on osx and cannot be explicitly
requested like additional security manager settings. So instead
of forking the CLI process directly the tests interact with a test
fixture that isn't bound by Elasticsearch's rules and *can* fork
it.
This forking of the CLI has a nice side effect: it forces us to
make sure that things like security and connection strings other
than `localhost:9200` work. The old test could and did work around
missing features like that. The new tests cannot so I added the
ability to set the connection string. Configuring usernames and
passwords was also not supported but I did not add support for
that, only created the failing test and marked it as `@AwaitsFix`.

* 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.

`gradle check -xforbiddenPatterns` now passes in jdbc.
This makes running the embedded HTTP server slightly more difficult,
you now have to add the following to your jvm arguments.
```
-ea -Dtests.rest.cluster=localhost:9200 -Dtests.embed.sql=true -Dtests.security.manager=false
```
Depending on your environment the embedded jdbc connection may give
spurious failures that look like:
```
org.elasticsearch.xpack.sql.jdbc.jdbc.JdbcException: RemoteTransportException[[node-0][127.0.0.1:9300][indices:data/read/search]]; nested: SearchPhaseExecutionException[]; nested: GeneralScriptException[Failed to compile inline script [( params.a0 > params.v0 ) && ( params.a1 > params.v1 )] using lang [painless]]; nested: CircuitBreakingException[[script] Too many dynamic script compilations within one minute, max: [15/min]; please use on-disk, indexed, or scripts with parameters instead; this limit can be changed by the [script.max_compilations_per_minute] setting];

```
`gradle check` works around this by setting `script.max_compilations_per_minute`
to `1000`.
Another change is that we no longer support loading the test data by
uncommenting some code. Instead we load the test data into Elaticsearch
before the first test and we deleted it after the last test. This is
so that tests that required different test data can interoperate with
eachother. The spec tests all use the same test data but the metadata
tests do not.
