Added CachingRealm to published artifacts so it can be used in custom realm
If the realm uses native role mappings and the security index health changes,
the realm caches are cleared. For example, they are cleared when the index
recovers from a red state, when the index is deleted, when the index becomes
outdated, and when the index becomes up-to-date.
Fixed a bug that could prevent auditing to a remote index if the remote
cluster was re-started at the same time as the audited cluster.
Removed AuthorityKeyIdentifier’s Issuer and Serial number from certificates
generated by certgen and certutil. This improves compatibility with
certificate verification in Kibana.
Proxies now use HTTP by default, which was the default prior to 6.0. This
fixes issues with HTTPS requests that tried to access proxies via HTTP.
Fixed the HTML sanitizer settings
(xpack.notification.email.html.sanitization.*), which were broken in 6.2. For
more information, see Watcher Settings.
