Heal and scale method support of lcm_user_data

Registered by renu rani

Currently creation of the stack parameter is a fixed process and user cannot do the customization.
The proposed solution to enable customization of stack parameters through the lcm_user_data script.
User can provide stack parameters through lcm_user_data script.

For example, at the time of scale, the desired_capacity value is rewritten as a Tacker process by setting up a get_param naming convention (VDU name_desired_capacity) on the HOT (Heat Orchestration Template) without going through the lcm_user_data script. Since desired_capacity is also in the scope of rewriting HOT with parameters, it needs to be modified so that the script of lcm_user_data can be used.
