Bump dependencies stream (#841)

* Bump Postgresql, Nginx and Redis versions
* pg12 --> pg13 upgrade path
* Set supported pg version as a variable to remain DRY
* Make deleting the old db data pvc after upgrade configurable
* Use labels to find the postgres pod

* backup/restore: fix postgres label selector value

We need to use the deployment_name variable for the postgres instance
name.
