* SQL: Remove instanceof checks for field retrieval
This removes the `instanceof` checks iterating through the columns determining

`FieldExtraction` that collects the fields needed in a builder. The builder can
then build the fields necessary from a `SearchSourceBuilder`.

support `JOIN`, we don't support `EXISTS`.

`SELECT DISTINCT foo FROM bar` is not yet implemented and was returning
an "unplanned item" error which isn't useful to users so I replaced it
with `SELECT DISTINCT is not yet supported`.
`SELECT foo, COUNT(*) FROM bar GROUP BY ALL foo` is not supported.
Specifically the `ALL` part. It is fairly esoteric so see [1] for what
it does. Regardless of what it does it is not widely supported and even
Microsoft's SQL Server has deprecated it so we should never support it.
Probably.

`ThreadLocal` variables have a tendency to complicate control flow,
especially if these variables are "context" variables. This PR drops the
`ThreadLocal` that SQL was using for its request context in favor of
delaying construction of the components that need the context until what
they need is ready.
This further simplifies things by passing to components what they need
rather than a larger context object. This is important because not all
of the context is ready at all parts of the request. In particular we
haven't resolved the index until long after the parsing stage, but the
parser wants to know the time zone.
This way of doing things does create a few more objects on each request
but those objects are fairly light and should die as soon as the SQL has
been translated to an Elasticsearch query.

SQL was adding scroll timeouts to aggregation only queries. At best this
is just confusing because we never scroll these queries. It *might*
leave behind a scroll context that we don't want. It is failing some new
validation that says that we have to have a `size` for every scroll
query.
Anyway, the simplest thing to do is to not put a scroll on aggregation
only queries.

This adds the remaining [matrix aggregations](https://www.elastic.co/guide/en/elasticsearch/reference/6.1/search-aggregations-matrix-stats-aggregation.html).
These aggregations aren't currently implemented due to the inter-plugin
communication not being set up, so they return "innerkey/matrix stats not

Fixes the error message that SQL produces when it sees unsupported
indexes. It was always returning all broken indexes as "unknown" even
though we have much better error messages. It was just throwing them
away.
I caught this originally when backporting to 6.x where we had a test
that we produced a useful error message when the user attempted to run
SQL on an index with more than one type. We couldn't run that in the
feature/sql branch because it is inside the full cluster restart tests
and the "old" version of Elasticsearch used in those tests in
feature/sql is 6.x which doesn't allow indexes with multiple types. When
I backported to 6.x the test failed because it hadn't been run before.
In addition to fixing that test and the problem, this adds another test
that will reveal the problem when run in the feature/sql and master
branch.

Previously I'd added tests for JDBC and CLI that I *thought* used SSL but they didn't! I wasn't careful...
Testing changes:
* Actually enable SSL/HTTPS in the `qa:sql:security:ssl` subproject.
* Rework how `RemoteCli` handles security. This allows us to configure SSL, the keystore, and the username and password in a much less error prone way.
* Fix up JDBC tests to properly use SSL.
* Allow the `CliFixture` to specify the keystore location.
* Switch `CliFixture` and `RemoteCli` from sending the password in the connection string to filling out the prompt for it.
* Have `CliFixture` also send the keystore password when a keystore is configured.
This makes the following production code changes:
* Allow the CLI to configure the keystore location with the `-k`/`-keystore_location` parameters.
* If the keystore location is configured then the CLI will prompt for the password.
* Allow the configuration of urls starting with `https`.
* Improve the exception thrown when the URL doesn't parse by adding a suppressed exception with the original parse error, before we tried to add `http://` to the front of it.

Original commit: elastic/x-pack-elasticsearch@6932db642c
Given that we get now filtered mappings directly from the get index API (in case security is configured with FLS), we don't need the security filter nor the filtered catalog. That means we can remove the delayed action support also from AuthorizationService and rather make SQLAction a composite action like others. It will be authorized as an action, but its indices won't be checked while that will happen with its inner actions (get index and search) which need to be properly authorized.
Also, SQLGetIndicesAction is not needed anymore, as its purpose was to retrieve the indices access resolver put in the context by the security plugin for delayed actions, which are not supported anymore.

SQL: Introduce PreAnalyze phase to resolve catalogs async
The new preanalyze phase collects all unresolved relations and tries
to resolve them as indices through typical async calls _before_ starting the analysis process.
The result is loaded into a catalog which is then passed to the analyzer.
While at it, the analyzer was made singleton and state across the engine
is done through SqlSession#currentContext().

Make sure that get index requests calls are locally executed by providing local flag.
Don't replace index/alias name with concrete index name in asCatalog response conversion. We need to preserve the original alias name for security, so it is reused in the subsequent search.

Get index is now executed instead of sql get indices, and sql get indices has been removed.
Also made cluster privileges more restrictive to make sure that cluster state calls are no longer executed.

SqlGetIndicesAction action is still needed in RestSqlJdbcAction (metaTable and metaColumn methods), where we can't at the moment call IndexResolver directly, as security (FLS) needs index resolver to be called as part of the execution of an indices action.

While we're fairly sure we're going to remove the binary protocol in the
long run, we're also fairly sure we're going to release the first
version of SQL with the binary protocol. One big problem with it is that
it blows up when it attempts to serialize fairly long strings. These
long strings are actually quite common in the CLI. They are also
possible in JDBC. I say "fairly long strings" because exactly how long
the strings has to be is kind of funky. It is based on the number of
bytes that it takes to encode the string, and the strings are encoded in
a utf-8-like encoding of utf-16 encoded string documented here:
https://docs.oracle.com/javase/7/docs/api/java/io/DataOutput.html#writeUTF(java.lang.String)
Anyway, this fixes the protocol for these "fairly long strings" by
chunking the strings and adding an extra 4 byte integer before each
string to count the number of chunks. After that 4 byte integer the
strings are serialized using the "normal" DataInput/DataOutput encoding,
the funny utf-8-like encoding of the utf-16 encoded string.

When an error response wasn't parseable we would through fairly obscure
error messages about what is wrong with it. Great if you are fixing a

Original commit: elastic/x-pack-elasticsearch@00e542afc8
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.
