* Started work on DRBD->get_next_resource(), that will eventually return the next free DRBD minor and TCP port numbers.

Browse Source 
* Fixed a bug in scan-drbd that was still looking for the scan_drbd_resource_uuid from the resource config file. Also added a check to see if 'scan-drbd::resource_status' directory exists before trying to read the files in it.

=head2 get_next_resource
This returns the next free DRBD minor number and the next free TCP port. The minor number is the first one found to be free. The TCP port is allocated in steps of three. That is to say, if the last used TCP port is '7790', then '7793' is considered the next free port. This is to ensure that if a DR host is added or used, the three adjacent ports are available for use in one resource configuration.
Minor numbers are not grouped as resources and volumes can be referenced by name, so the DRBD minor number is less important for human users.
my ($free_minor, $free_port) = $anvil->DRBD->get_next_resource({anvil_uuid => "a5ae5242-e9d3-46c9-9ce8-306855aa56db"})
If there is a problem, two empty strings will be returned.
Parameters;
=head3 anvil_uuid (required)
This is the Anvil! in which we're looking for the next free resources.
