Public bug reported:

Oslo.config uses re.search() to check config values against the allowed
regex. This checks if the regex matches anywhere in the string, rather
than checking if the entire string matches the regex.

Nova has three config options that appear as if the entire string should match the given regex:
* DEFAULT.instance_usage_audit_period
* cinder.catalog_info
* serial_console.port_range

However, these are not bounded with ^ and $ to ensure the entire string
matches.
