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

This change adds some debug and trace logging when we look up role names, to explain how each role was resolved.
At the moment we have very little insight into how roles are being resolved which can make it difficult to diagnose some issues.

Register LoggingAuditTrail as a ClusterStateListener.
Avoid querying for the localNode while on the ClusterStateApplier thread,
which tripps assertion. This can happen when logging audit events that

If the KeyStoreWrapper is closed, then we cannot validate secure settings (because we no longer have access to them)
The Realm group setting uses the "validate" method to ensure that child settings are correct, but it must ignore secure settings as it might get called
after startup (e.g. during a settings diff)

This commit uses SPI to get the list of system wide reserved roles in
security. It does not yet split out the RoleDescriptor to a common
location so the implementing services still depend on security. Each
role, however, only depends on its own feature as well as security.

This change fixes a problem that would cause job deletion to fail if ANY
index had a block on it, e.g. read-only.
The problem was that we were requesting the job aliases be deleted from
ALL indices in the system due to a misunderstanding with the format of the
get_aliases response. This didn't usually cause any noticable effects, as
only the ML indices would have the aliases. But in the case of a read-only
index it would cause an error, leading to unnecessary failure of the job
deletion.

Following the changes of elastic/x-pack-elasticsearch#2975 the hard limit on the number of ML jobs
per node is no longer the only limiting factor. Additionally there is
now a limit based on the estimated memory usage of the jobs, and this is
expected to provide a more sensible limit that accounts for differing
resource requirements per job.
As a result, it makes sense to raise the default for the hard limit on
the number of jobs, on the assumption that the memory limit will prevent
the node becoming overloaded if an attempt is made to run many large jobs.
Increasing the hard limit will allow more small jobs to be run than was
previously the case by default.
Of course, this change to the default will have no effect for customers
who have already overridden the default in their config files.

The issue here is that if the first search request fails
(initScroll), then we do not have a scroll_id. However,
in order to retry the search, we reset the scroll. That
involves clearing the current search, but since we do
not have a scroll_id, the clear scroll request fails.
We end up reporting the failure for the scroll clearing,
rather than the actual problem.
This commit fixes that by avoiding clearing the scroll
when the scroll_id is null.

This commit removes the KnownActionsTests as it no longer serves the intended purpose of catching
actions/handlers added to elasticsearch that security needs to be aware of. Today, it is common
for this test to break the build and as a mechanical response developers just add to the actions
or handlers file to get the build green again.

In order to support the repository split, this changes the
`AbstractWatcherIntegrationTestCase` to not run with security enabled.
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.

This change applies the same pattern that was applied in elastic/x-pack-elasticsearch#3054 to the
ML batched results iterators, which are used to scroll through ML results
during some internal ML implementation details, such as renormalization
and nightly maintenance.
Additionally the thread context is reset before submitting the results
processor to a thread pool, to avoid masking the problem in situations
where the user opening the job coincidentally had workable permissions.

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.

Add SSL tests against Elasticsearch because that is what actually needs

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.

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.
