The "multipath -C <mpath_name>" command waits for the multipath
device map to be ready for I/O. This is useful in preventing race
conditions when we are trying to write to the multipath device
before it is ready for I/O.
We added 2 new config options to make the wait time configurable,
1. wait_mpath_device_attempts - defaults to 4 attempts
2. wait_mpath_device_interval - defaults to 1 second
