As per the new licensing change for Elasticsearch and Kibana this commit
moves existing Apache 2.0 licensed source code to the new dual license
SSPL+Elastic license 2.0. In addition, existing x-pack code now uses
the new version 2.0 of the Elastic license. Full changes include:
- Updating LICENSE and NOTICE files throughout the code base, as well
as those packaged in our published artifacts
- Update IDE integration to now use the new license header on newly
created source files
- Remove references to the "OSS" distribution from our documentation
- Update build time verification checks to no longer allow Apache 2.0
license header in Elasticsearch source code
- Replace all existing Apache 2.0 license headers for non-xpack code
with updated header (vendored code with Apache 2.0 headers obviously
remains the same).
- Replace all Elastic license 1.0 headers with new 2.0 header in xpack.
For all OSS plugins (except repository-* and discovery-*) integTest
task is now a no-op and all of the tests are now executed via a test,
yamlRestTest, javaRestTest, or internalClusterTest.
This commit does NOT convert the discovery-* and repository-* since they
are bit more complex then the rest of tests and this PR is large enough.
Those plugins will be addressed in a future PR(s).
This commit also fixes a minor issue that did not copy the rest api
for projects that only had YAML TEST tests.

Today, a setting can declare that its validity depends on the values of other
related settings. However, the validity of a setting is not always checked
against the correct values of its dependent settings because those settings'
correct values may not be available when the validator runs.
This commit separates the validation of a settings updates into two phases,
with separate methods on the `Setting.Validator` interface. In the first phase
the setting's validity is checked in isolation, and in the second phase it is
checked again against the values of its related settings. Most settings only
use the first phase, and only the few settings with dependencies make use of
the second phase.
This pull request replaces the jvm-example plugin (from the jvm/site plugins era) by two new plugins: a custom-settings that shows how to register and use custom settings (including secured settings) in a plugin, and rest-handler plugin that shows how to register a rest handler.
The two plugins now reside in the plugins/examples project. They can serve as sample plugins for users, a special attention has been put on documentation. The packaging tests have been adapted to use the custom-settings plugin.
