add configurable timeouts for DB sync

This patch integrates with the db_sync_timeout
parameter recently added to puppet-nova
and puppet-neutron in
I6b30a4d9e3ca25d9a473e4eb614a8769fa4567e7, which allow for the full
db_sync install to have more time than just Pupppet's
default of 300 seconds.   Ultimately, similar timeouts
can be added for all other projects that feature
db sync phases, however Nova and Neutron are currently
the ones that are known to time out in some
environments.

Closes-bug: #1661100
