Subject: [PATCH] Support instance-minor pairing in the DRBD collector
This commits enables the DRBD data collector to use the Confd client to
gather information about the pairing between DRBD minors and instances.
For testing purposes, the DRBD data collector now requires either zero
or two parameters: one is the DRBD file, one is the pairings file.
When no parameter is passed, the collector is in "production mode" and takes
the data from /proc/drbd and from the Confd client.
The shell tests of mon-collector are updated accordingly.

Collects the information about the version and status of the DRBD kernel
module, and of the disks it is managing.
-If *status-file* is specified, the status will be read from that file.
-Otherwise, the collector will read it from /proc/drbd.
+If *status-file* and *pairing-file* are specified, the status and the
+instance-minor paring information will be read from those files.
+Otherwise, the collector will read them, respectively, from /proc/drbd
+and from the Confd server.
+
+The options that can be passed to the DRBD collector are as follows:
+
+-s *status-file*, \--drbd-status=*status-file*
+ Read the DRBD status from the specified file instead of /proc/drbd.
+
+-p *pairing-file*, \--drbd-pairing=*pairing-file*
+ Read the information about the pairing between instances and DRBD minors
+ from the specified file instead of asking the Confd servers for them.
