Sync openstack.common.local from oslo

Browse Source 
`local` has a broken TLS symbol - strong_store, fixed in oslo some time ago in
Ib544be1485823f6c619312fdee5a04031f48bbb4. All direct and indirect
(lockutils and rpc) usages of strong_store might be potentially affected.
Original change to Nova: If4dd973acc23921dbc2bc69bb76225deb2802dad

Closes-Bug: #1254046
Change-Id: I934149092cacaaa78009565b6d8a6ba348c2dbe4
