iSCSI attach/detach speed is not optimal due to the presence of a big critical section in the os-brick code.

This section can be reduced using a combination of exclusive and shared locking on the same file lock.

The work should be done in upstream os-brick and then get it here once it is released, but if it takes a while to get merged we could consider carrying the patch downstream in Ember-CSI containers until it does.
