Adds a mode parameter to all SQL-related requests. The mode parameter is used for license checks as well as to define the response content. For now only two modes are supported plain (default) and jdbc. We will add other modes in the future as we add more clients.

* 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

The /_sql endpoint now returns the results in the text format by default. Structured formats are also supported using the format parameter or accept header similar to _cat endpoints.

I realized that we weren't running our DatabaseMetaData tests. One thing led to another and I made these changes:
1. Got the DatabaseMetaData tests running in all three of our QA projects.
2. Fixed the SecurityCatalogFilter to work with `SqlGetIndicesAction`. It worked before, but only for requests that were a `SqlAction` as well as `SqlGetIndicesAction`.
3. Added security test for the JDBC DatabaseMetaData requests. These mirror exactly the security tests that we use for `SHOW TABLES` and `DESCRIBE` but cover the JDBC actions.

Adds docs for the REST API, translate API, the CLI, and JDBC.
Next we need to add more example queries and documentation for our
extensions.

We weren't returning errors correctly from the server
or catching them correctly in the CLI. This fixes that
and adds simple integration tests.

* Switch `ResultSet#getFetchSize` from returning the *requested*
fetch size to returning the size of the current page of results.
For scrolling searches without parent/child this'll match the
requested fetch size but for other things it won't. The nice thing
about this is that it lets us tell users a thing to look at if
they are wondering why they are using a bunch of memory.
* Remove all the entire JDBC action and implement it on the REST
layer instead.
* Create some code that can be shared between the cli and jdbc
actions to properly handle errors and request deserialization so
there isn't as much copy and paste between the two. This helps
because it calls out explicitly the places where they are different.
* I have not moved the CLI REST handle to shared code because
I think it'd be clearer to make that change in a followup PR.
* There is now no more need for constructs that allow iterating
all of the results in the same request. I have not removed these
because I feel that that cleanup is big enough to deserve its own
PR.
Original commit: elastic/x-pack-elasticsearch@3b12afd11c
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`.

This shuffles all of SQL's QA tests into the `qa/sql` directory, moving
some shared resources into the new `qa:sql` project. It also rigs up
testing of the rest SQL interface in all the sql qa configurations:
without security, with security, and against multiple nodes.
I've had to make some modifications to how we handle the audit log
because it has gotten pretty slow. If these modifications turn out to
not be fast enough then I'll change the test to querying the log files
and drop the audit log index entirely but the index seems to be holding
out for now.
