Create automated deployment scripts for central services

Impact of the new feature
WMCore Central Services deployment process

Is your feature request related to a problem? Please describe.
Even though we are supposed to move to Kubernetes soon the following is still a valid development strategy:

• Develop in a featured branch a new component (which may also require a change in the deployment repository)
• Make an initial PR to WMCore repository ready to be tested [1]
• Implement the needed changes in the configuration and deployment scripts in dmwm
• Make an initial PR to dmwm/deployment repository ready to be tested [2]
• Deploy central services using the procedure from [3] while patching them with the aforementioned PRs
• Test/Validate your service

Which is still a process that takes time and is actually quite error prone.

Describe the solution you'd like
I would like t have a script similar to the deployment script we have for WMAgent [4] which would do all of the above based on a set of command line parameters

Do nothing and Continue working as before
