"standby clone": add --recovery-conf-only option

This will generate "recovery.conf" for an existing standby.

Typical use-case is a standby cloned manually from an external data
source (e.g. Barman), where "recovery.conf" needs to be created
(and if required a replication slot).

The --dry-run option will check the pre-requisites but not actually
create "recovery.conf" or a replication slot.

This requires that the upstream node is running, a replication connection
can be made and if required a replication slot can be created.

Implements GitHub #382.
