SOLR-15101: Add list/delete APIs for incremental backups (#2336)
SOLR-13608 introduces a new "incremental" backup format, which allows
storage of multiple backup "points" in the same location. This
development introduces a need for APIs to manage these potentially
plural backups.
This commit introduces /admin/collections?action=LISTBACKUPS and
/admin/collections?action=DELETEBACKUP to handle these backups.

> Project: Solr

> SIP-12 lays out a plan for adding support for incremental backups to Solr.
> At a high level, the idea is that Solr will be able to store multiple backups
> in the same location, and backups beyond the first one will only upload those
> files that were not uploaded by previous backups.
> This involves changes to the file structure within a particular backup
> location. It also entails changes to some of the backup/restore API
> parameters and semantics, to accommodate storing multiple backups in the same
> place, etc.
> This ticket covers the changes required for this functionality, as described
> in SIP-12 unless mentioned specifically below. It does not implement all of
> [SIP-12.|https://cwiki.apache.org/confluence/display/SOLR/SIP-12%3A+Incremental+Backup+and+Restore]
> Same-collection-restoration, support for popular proprietary blob stores,
> etc. are left for separate tickets in an attempt to keep PRs manageable and
> conceptually cohesive.
