Add standby restore type.

Browse Source 
This restore type automatically adds standby_mode=on to recovery.conf.

This could be accomplished previously by setting --recovery-option=standby_mode=on but PostgreSQL 12 requires standby mode to be enabled by a special file named standby.signal.

The new restore type allows us to maintain a common interface between PostgreSQL versions.
