James Slagle 7483b62332 Automatically run overcloud export when using ephemeral heat
The overcloud export environment will be automatically created when
using ephemeral heat. Since the stack is ephemeral, we need to go ahead
and do the export before stopping Heat. While we backup the heat db so
we have the stack saved if needed, it's just eaiser and eliminates a
manual step to do the export if we do it automatically.
