Add REST API to create snapshots of Lucene indexes

To safely backup indexes in Gerrit, Gerrit had to be shut down.
This is required, since an index consists of multiple files and
copying those while the index changes can lead to a broken
inconsistent state of the index. Lucene however provides a
mechanism to create a snapshot at runtime.

This change adds REST API endpoints to create snapshots of all
write indexes of a given index type. These snapshots will be
stored on the server in the Gerrit site under `$SITE/index/snapshots`
and can be used to restore the index state.
