[pve-devel] [PATCH storage] Automatically create/delete CEPH keyring when adding/deleting RBD Storage

[Caspar Smit]

When adding an RBD storage to Proxmox this patch checks if the
/etc/pve/priv/ceph dir exists, if not it will create it.
The the client.admin keyring will be copied to it with the
correct name of the storage (storeid.keyring)

When deleting an RBD storage the keyring file will be removed.
