Tim Vernum 286d62f00e Don't clear realm-cache during security upgrade on basic license (elastic/elasticsearch#4806)
If a user has a basic license, but previously had a full-featured license (e.g. a trial license that expired) then they may have .security index that needs to be migrated even though security is not allowed under their license.

This change makes the clearing of the realm-cache conditional on the license state. If X-Pack is running on a license that does not allow auth, then, when the `logstash_system` user is disabled as part of an upgrade migration, the cache is not cleared.

This change also fix a bug whereby a mapping update could take place even if a data migration was in progress, which could cause the `logstash_system` user to be temporarily enabled when it ought not be.

= Elasticsearch X Pack

A set of Elastic's commercial plugins:

- License
- Security
- Watcher
- Monitoring

= Setup
You must checkout x-pack and elasticsearch with a specific directory structure. The
elasticsearch checkout will be used when building x-pack. The structure is:

- /path/to/elastic/elasticsearch
- /path/to/elastic/elasticsearch-extra/x-pack

= 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/Logstash side of x-plugins, you can force gradle to skip building kibana and/or Logstash by adding
  `xpack.kibana.build=false`/`xpack.logstash.build=false` to your `~/.gradle/gradle.properties`. Alternatively you add `-Pxpack.kibana.build=false` or `-Pxpack.logstash.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`).
