staging - journal0 needs more space

Journal0 raised the 10% free disk space alert.

The kafka disk is already a 500Go disk on ceph, so replicated 3 times.

Instead of increasing the disk, it could be the occasion to move the journal service to a server with more storage like db1.staging or storage1.staging

IMO storage1 is a better choice as db1 will probably need to also host cassandra when it will be deployed.

so we will have: storage1:

• storage
• objstorage
• kafka db1:
• postgresql dbs
• cassandra
