Peter Razumovsky 6ec2759324 Add a config option to enable Convergence
This patch adds column 'convergence' to stack table
and configuration option 'convergence_engine'. If
'convergence_engine' equals True, new stacks are created,
updated and backuped with convergence column equals
True and old stacks are updated and backuped with
convergence column equals False. Otherwise convergence
column equals False.
