Parsons, Cliff (cp769u) 5a2babd514 Backup/restore enhancements
This patchset introduces the framework by which all OSH-based database
systems can use to backup and restore their databases. The framework
is refactored from the Postgresql backup and restore logic. This will
prevent alot of code duplication in the backup restore scripts across
each cluster.

In the process, some improvements needed to be made:
1) Removing the need for 2 separate containers to do the backup
   and restore work to a remote gateway. This simplifies the design
   and enables a higher level of robustness.
2) Adding separate "days to keep" config value for remote backup files,
   as there may be different requirements for the remote files than the
   local backup files.
3) Adding capability to send Storage_Policy when creating the remote
   RGW swift container.
4) Making coding style improvement for readability and maintainability.
5) Fixing a deployment bug that occurs when remote backup is disabled.
