Months ago SQL used `Desktop#open` to view the results of graphviz
description of plans. We've since removed this feature in favor of just
writing the file. So now we can build the CLI against the same java
profile that we build everything agianst.

* Starts to build the list of supported functions, adding links to
wikipedia when there is any doubt what the functions mean.
* Extracts an example of using the function from the test suite.
* Explicitly calls out how we round (half up) because there are
lots of ways to round.

This adds support for (almost) all of the options that the `query_string` query
supports.
Additionally, it reverts back to the default operator of `OR` rather than `AND`
for the `QUERY()` query.

We don't support the SQL `EXISTS` keyword. It looks like:
```
SELECT * FROM test WHERE EXISTS (SELECT * FROM foo WHERE test.id =
foo.id)
```
It is basically a `JOIN` that doesn't return columns. Since we don't
support `JOIN`, we don't support `EXISTS`.
This PR improves the error message from "unresolved blah blah blah" to
"EXISTS is not yet supported".

`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.

Since matrix aggs module isn't on the classpath at runtime, we shouldn't
compile with it on the classpath. Doing so makes it possible for us to
die with dignity when we can't load the class. Which happens right now.

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.

* Add remaining matrix aggregations
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
handled (yet)".
For matrix aggs that share a name with an existing aggregation (like 'count'),
they have be prefixed with "matrix_", so, "matrix_count", "matrix_mean", and
"matrix_variance".

When running `gradle run` at the top level (at least with Gradle 4.4) it
attempts to run multiple instances of the server, causing the run to fail since
they can't both bind to 9200/9300.
This renames the tasks for the `qa` directories to be `runqa` and the task for
the `cli` directory to be `runcli`.

`UnresolvedRelation`'s equality test would sometimes not properly mutate
the object under test. This is because `ESTestCase#randomValueOtherThan`
will only run its provider one time if passed `null` for the "other

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.

I have no idea why this logic was only looking at snapshot JARs (what is
suppose to happen in production?). This breaks the release tests though
which we really need to have stable. This commit fixes this by also
considering non-snapshot JARs.

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.

Given that the Catalog was only ever used to hold a single index, the corresponding abstraction can be removed in favour of the abstraction that it holds, namely `GetIndexResult`.
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.
This commit kind of reverts elastic/x-pack-elasticsearch#2162, as it is now possible to integrate with security out-of-the-box

While working on cursor cleanup, I realized that we still have two ways to serialize the cursor and the second way doesn't contain the cursor version (only client version, that can be potentially different from the cursor version). This commit switches to the unified way of serializing the cursor.
This is a follow up for elastic/x-pack-elasticsearch#3064.

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().
Commit missing fix
Fix typo
Fix license
Fix line length
remove redundant static modifier
Remove redundant generics type
Rename catalogResolver instance member to indexResolver
Fix translate action to return a response through the listener, it hangs otherwise
IndexResolver improvements
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.
Update roles and actions names for security tests
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.
Fix most of the security IT tests
indices options are now unified, always lenient. The only situation where we get authorization exception back is when the user is not authorized for the sql action (besides for which indices).
Improve SessionContext handling
Fix context being invalid in non-executable phases
Make Explain & Debug command fully async
Resolve checkstyle error about redundant modifiers
Temporarily restore SqlGetIndicesAction
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. Once mappings are returned filtered, delayed action and the security filter will go away, as well as SqlGetIndicesAction.
SqlGetIndicesAction doesn't need to be a delayed action, my bad

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.

Instead of returning "error response" objects and then translating them
into SQL exceptions this just throws the SQL exceptions directly. This
means the CLI catches exceptions and prints out the messages which isn't
ideal if this were hot code but it isn't and this is a much simpler way
of doing things.
