Allow db sync timeouts to be configurable

As Openstack projects continue to have longer database migration
chains, the Puppet default timeout of 300 seconds for an execution
is becoming too short a duration on some hardware, leading to timeouts.
As projects continue to add more migration scripts without pruning
the base, timeouts will continue to become more frequent unless
this time can be expanded.
