The sorcery astDB wizzard does not handle regex correctly if the pattern begins with an anchor character.

This patch attempts to convert the anchored regex pattern to a prefix pattern supported by astDB for performance reasons.  If it is not able to convert the pattern it gets all astDB members of the family and then does a normal regex pattern matching on the resulting records retrieved.

Diff: https://reviewboard.asterisk.org/r/3161/diff/


Simple regex patterns that are just prefixes are converted and the astDB just fetches the matching records.  More complex patterns fallback to getting all astDB family records and searching them by regex.
