Mike Pittaro 2fbccc0c69 Clean stale lockfiles on service startup : fixes bug 785955
Adds cleanup_files_locks() to nova/utils, which cleans up stale locks
left behind after process failures.

Adds a call to clean up locks on service startup for nova-api, nova-cert,
nova-compute, nova-network, nova-objectstore, and nova-scheduler.

Adds tools/clean_file_locks.py, which can be used to manually clean
stale locks.
