Code Issues Proposed changes

Ensure a functional database connection

Browse Source 
Allow retrying database connection in get_engine() at an interval.  Resolves
the issue of nova components erroring at startup if a database connection is
unavailable, particularly at boot. Borrowed from a similar commit to glance,
(https://review.openstack.org/#change,5552).

Fixes Bug #959426 for nova.

Update: * Properly return an engine (fixes tests)
        * Setting sql_max_retries to -1 will retry infinitely
        * Bumped options count in nova.conf.sample
        * i18n log warning
        * Add note to flag help about -1 == infinite
        * Pep8 fix
