From: Chen Qi <Qi.Chen@windriver.com>

We want to be able to do stable version upgrade for recipes. For
example, 1.0.0 -> 1.0.1 instead of 1.0.0 -> 1.1.0.

To to this, we need an extra paramter to latest_versionstring
so that we are able to filter out the versions we need. Using regex
has the advantage of adapting to different version schemes.
