Jay Modi ffeaea0663 Migrate authentication calls to be asynchronous
This commit migrates the actual authentication calls that are performed by internal realms
to be asynchronous so that we do not execute blocking calls on network threads. The realms
that used LDAP were especially bad as they can issue many different requests and/or open
multiple connections per authentication attempt.

The LdapRealm now uses the ThreadPool to fork a thread for authentication. This is necessary
because a LDAP bind operation is not allowed to be performed asynchronously and must be done
in a blocking manner. After the bind request has completed, all other requests can be done
asynchrnously. The LdapUtils class now provides asynchronous methods for searching and also
includes the handling of referral following as automated following is not supported by
UnboundID when using the asynchronous calls.

= 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`).
