RGW metadata search backed by ElasticSearch now supports end user requests service via RGW itself, and also supports custom metadata fields. A query language was defined and a set of RESTful APIs were created for users to be able to search objects by their metadata. New APIs that allow control of custom metadata fields were also added.

BlueStore for performance reasons.) FIXME DOCS
* *Erasure coded* pools now have full support for *overwrites*,
allowing them to be used with RBD and CephFS.
