[Bug 1325759] Re: start_up uses database lock outside of transaction

[Greg Lutostanski]

** Description changed:

+ [Impact]
+  * When using new locking code, this is used to prevent an error on maas server startup when asking for a lock when not in a transaction
+ 
+ [Testcase]
+  * Run included tests in test_start_up.py
+ 
+ [Regression Potential]
+  * Minimal
