daemon: Add a tunable to enable automatic database priority setting
Samba versions 3.6.x and older do not set the database priority.
This can cause deadlock between Samba and CTDB since the locking order
of database will be different. A hack was added for automatic promotion
of priority for specific databases to avoid deadlock. This code should
not be invoked with Samba version 4.x which correctly specifies the
priority for each database.
