Description of problem:
Currently colonizer deployment asks for multiple inputs from admin to deploy gluster. However below are the problems
1)if a manual mistake is made, we need to restart whole deployment again, which is a bit cumbersome
2)it can be a bit cumbersome to even having to enter multiple details through prompts.
Instead we can have an option, where user enters all the required details, in a common template form say an yaml file(like the one where we can mention volume name, disks etc) and then the user just have to run the script, and wait for colonizer to deploy the cluster. No more prompts no more accidentally erroneous inputs to be fed.
the template yaml can even have the instructions at each field to be entered
Version-Release number of selected component (if applicable):
I have opened to upstream issues to track separately features for re-input of fields and for unattended installation via template file.
Closing all Colonizer BZs (as DEFERRED) as we do not intend to work on them for the time being.
