jaymode 7d78911082 security: limit the size of the role store cache
Previously the roles store cache was unbounded as it was a just using a ConcurrentHashMap,
which could lead to excessive memory usage in cases where there are a large number of roles
as we tried to eagerly load the roles into the cache if they were not present. The roles store now
loads roles on demand and caches them for a finite period of time.

Additionally, the background polling of roles has been removed to reduce complexity. A best effort
attempt is made to clear the roles cache upon modification and if necessary the cache can be
cleared manually.

= Elasticsearch X Plugins

A set of Elastic's commercial plugins:

- License
- Security
- Watcher
- Monitoring

= Setup
You must checkout x-plugins and elasticsearch in the same directory as siblings. This
elasticsearch checkout will be used when building x-plugins.

= Build

- Run unit tests:
+
[source, txt]
-----
gradle clean test
-----

- Run all tests:
+
[source, txt]
-----
gradle clean check
-----

- Run integration tests:
+
[source, txt]
-----
gradle clean integTest
-----

- Package X-Pack (wihtout running tests)
+
[source, txt]
-----
gradle clean assemble
-----

- Install X-Pack (wihtout running tests)
+
[source, txt]
-----
gradle clean install
-----

- If you don't work on the UI side of x-plugins, you can force gradle to skip building kibana by adding
  `xpack.kibana.build=false` to your `~/.gradle/gradle.properties`. Alternatively you add `-Pxpack.kibana.build=false`
  on the command line if you only want to do this on individual builds (or `-Pxpack.kibana.build=true` if you need to
  override having added this to your `gradle.properties`).
