Heat engine settings required for Undercloud

This patch adds several new heat engine setting that are required
in order to configure a fully working Heat engine in the undercloud.

New parameters have been added for the max resources and convergence
settings. I've hard coded the max stack depth at 6 which matches our
undercloud and should be fine as a default setting I think (would
rarely need overridden).
