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.

Tests that rely on the security index and security index template being present should not remove
the template between tests as this can cause test failures. The template upgrade service relies
on cluster state updates to trigger the template being added after a delete, but there is a
scenario where the test will just wait for template that never shows up as there is no cluster
state update in that time. Instead of fighting ourselves, we should just leave the template in
place.

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.

* Tests: Replace YAML tests with ESTestRestCase to be able to wait for events
The YAML tests did not have any possibility to wait for the watches to
be created. A hard ten second timeout was used, that could not be
aborted, by simulating a sleep when waiting for a number of nodes that
never occured in the cluster.
This commit replaces those waiting YAML tests with ESRestTestCases, that
use `assertBusy()` to exit early once the watches have been added. Also
this increases the wait time if needed, as these tests tend to fail on
CI.

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

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().

In order to support the repository split, this changes the

We have a dedicated QA project called `smoke-test-watcher-with-security`,
where tests that explicitely need security should be running.
This commit removes the possibility to enable security as part of the
test case. In addition some tests have been moved over to the dedicated
project.
In addition the `timewarp` functionality cannot be configured with a
system property anymore. This would not have worked anyway, because
tests were already dependent on that functionality and did not have any
other means of running. A bit of redundant code was removed due to this.

Original commit: elastic/x-pack-elasticsearch@4353793b83
The chained input in watcher is a useful feature to
call several endpoints before execution a condition.
However it was pretty hard to modify data from a previous
input in order to be able to execute it in another input.
This commit adds a another input, called a `transform` input,
which allows you to do a transform as another input in a chained
input.
See this example
```
"input" : {
"chain" : {
"inputs" : [ <1>
{
"first" : {
"simple" : { "path" : "/_search" }
}
},
{
"second" : {
"transform" : {
"script" : "return [ 'path' : 'ctx.payload.first.path' + '/' ]"
}
}
},
{
"third" : {
"http" : {
"request" : {
"host" : "localhost",
"port" : 9200,
"path" : "{{ctx.payload.second.path}}" <2>
}
}
}
}
]
}
}
```
This allows for far more flexibility before executing the next input in a chained
one.
Original commit: elastic/x-pack-elasticsearch@3af9ba6e9b
In order to be able to execute a watch as the user, who stored the
watch, this commit stores certain headers of the thread context, that
was used when the watch was stored.
Upon loading the watch the headers are loaded and applied for the
following watcher execution features
* search transform
* search input
* index action
A special case is the execute watch API, which overrides the headers loaded
from the watch with the one of the current request, so that a user
cannot execute this watch with other privileges of the user who stored it.
Only the headers "es-security-runas-user", "_xpack_security_authentication" are
copied for now, as those are needed for our security features.
The headers are stored in watch status in the watch and are not returned by default,
when the GET Watch API is used. A search reveals those of course.

This change removes the InternalClient and the InternalSecurityClient. These are replaced with
usage of the ThreadContext and a transient value, `action.origin`, to indicate which component the

request is executed as the proper user. This work comes from elastic/x-pack-elasticsearch#2808 where @s1monw suggested
that we do this.
While working on this, I came across index template registries and rather than updating them to use
the new method, I replaced the ML one with the template upgrade framework so that we could
remove this template registry. The watcher template registry is still needed as the template must be
updated for rolling upgrades to work (see elastic/x-pack-elasticsearch#2950).

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.

This commit removes the FAILED state for the IndexAuditTrail so that we always try to keep starting
the service. Previously, on any exception during startup we moved to a failed state and never tried
to start again. The users only option was to restart the node. This was problematic in the case of
large clusters as there could be common timeouts of cluster state listeners that would cause the
startup of this service to fail.
Additionally, the logic in the IndexAuditTrail to update the template on the current cluster has
been removed and replaced with the use of the TemplateUpgradeService. However, we still need to
maintain the ability to determine if a template on a remote cluster should be PUT. To avoid always
PUTing the template, the version field has been added so it only needs to be PUT once on upgrade.
Finally, the default queue size has been increased as this is another common issue that users hit
with high traffic clusters.
