Draft: loopy unpacking and multi packing
Current implementation of persistency configures a packer and unpacker for each location. This MR changes this to:
- one packer per object type
- each unpacker for a given location also unpacks all linked locations if they are not unpacked already. This will allow to request a location to be unpacked individually.
- Packing and unpacking configurations are simplified. PersistRecoConf is removed as most of it's functionality is not needed anymore.
To go with Moore!1638 (merged)
Needs DaVinci MR
