085e6fc55e
Adds a new command under the tripleo namespace for launching the all in one heat-all process in the foreground. The new command reuses the code from heat_launcher.py already in place for the tripleo deploy commands. Launching the heat-all process separately from tripleo deploy allows for easily spinning up a heat-all environment for stack creation and generating the config-download ansible content for development and test.
