settings.production: Allow the use of azure backend if defined
requested to merge ardumont/swh-deposit:adapt-deposit-configuration-and-allow-different-backend into master
This:
- adapts the deposit to allow (optionally) the use of remote azure backend (through the settings.production) [1]
- adapts accordingly the deposit private api part which checks or reads the stored archives
Refs. swh/infra/sysadm-environment#5129 (closed)
[1] Otherwise, that needs overcomplicated indirections in the chart deployment
