* Warn users if security is implicitly disabled
Elasticsearch has security features implicitly disabled by default for
Basic and Trial licenses, unless explicitly set in the configuration
file.
This may be good for onboarding, but it also lead to unintended insecure
clusters.
This change introduces clear warnings when security features are
implicitly disabled.
- a warning header in each REST response if security is implicitly
disabled;
- a log message during cluster boot.
As a follow-up of moving runtime fields to server, we would like to remove the runtime field xpack plugin portions that are left.
This commit moves the runtime-fields/qa module to x-pack/qa/runtime-fields. Runtime fields are no longer part of x-pack, but their qa tests involve testing with security, async search, which require x-pack, hence their qa tests are left under x-pack.
