Code Issues Proposed changes

Make nova server user_data format configurable 

Nova server property user_data_format default equals to
HEAT_CFNTOOLS since resource creation, so there's time to
move on - this format currently still used, but by no means all.
So add config option to easier changing default user_data_format
for flexible configuration of desired heat behaviour.

Now for specifying user_data_format default value, need just set
config option default_user_data_format equals to
HEAT_CFNTOOLS/RAW/SOFTWARE_CONFIG (underline as necessary) in default
section of heat config file.
