This commit forbids the changing of thread pool types for any thread
pool. The motivation here is that these are expert settings with
little practical advantage.

The gradle task to generate plugin properties files now is a simple copy
with expansion (ie maven filtering). It also no longer depends on
compiling.

IndexQueryParserService is only a factory for QueryShardContext instances
which are not even bound to a shard. The service only forwards dependencies and even
references node level service directly which makes dependency seperation on shard,
index and node level hard. This commit removes the service entirely, folds the creation
of QueryShardContext into IndexShard which is it's logical place and detaches the
ClusterService needed for index name matching during query parsing with a simple predicate
interface on IndexSettings.
This adds a generated-resources dir that the plugin properties are
generated into. This must be outside of the build dir, since intellij
has build as "excluded".

When generating a try-catch block, the eclipse default is something like this:
```
try {
something();
} catch (Exception e) {
// TODO: auto-generated stub
e.printStackTrace();
}
which is terrible, so the ES eclipse changes this to rethrow a RuntimeException instead.
```
try {
something();
} catch (Exception e) {
throw new RuntimeException();
}
```
Unfortunately, this loses the original exception entirely, instead it should be:
```
try {
something();
} catch (Exception e) {
throw new RuntimeException(e);
}
```
This PR adds a randomized test to the query test base class
that mutates an otherwise correct query by adding an additional
object into the query hierarchy. Doing so makes the query illegal
and should trigger some kind of exception. The new test revelead
that some query parsers quietly return queries when called with
such an illegal query. Those are also fixed here.

Similarly to what we did with the search api, we can now also move query parsing on the coordinating node for the validate query api. Given that the explain api is a single shard operation (compared to search which is instead a broadcast operation), this doesn't change a lot in how the api works internally. The main benefit is that we can simplify the java api by requiring a structured query object to be provided rather than a bytes array that will get parsed on the data node. Previously if you specified a QueryBuilder it would be serialized in json format and would get reparsed on the data node, while now it doesn't go through parsing anymore (as expected), given that after the query-refactoring we are able to properly stream queries natively. Note that the WrapperQueryBuilder can be used from the java api to provide a query as a string, in that case the actual parsing of the inner query will happen on the data node.

The RR gradle plugin is at
https://github.com/randomizedtesting/gradle-randomized-testing-plugin.
However, we currently have a copy of this, since the plugin is still in
heavy development. This change moves the files around so they can be
copied directly from the elasticsearch fork to that repo, for ease of
syncing.
Removes the mapping transform feature which when used made debugging very
difficult. Users should transform their documents on the way into
Elasticsearch rather than having Elasticsearch do it.
