Bug Description
Gorka noticed this in reviewing a change to os_brick/
create_hostnqn() checks for the existence of a file containing a previously generated hostnqn, and if it's not there, generates a new one and writes the file. This function needs a file lock, because 2 threads/processes could be checking for the existence of the file, not find it, and both proceed to create the hostnqn.
