Prepare the vault vm to expose the vault api.
The vault api is plugged to:
- db in prado
- "azure" objstorage
- "remote" storage already setuped in azure (storage0)
The objstorage is plugged to an azure blobstorage (as defined in D1495)
- As the db used is no longer installed on the same node, the postgres profile has been removed from the vault role
- The objstorage cache backend was exposed but unused, this was removed. As such, the vault role has been updated to remove the objstorage profile as well.
