At the moment we build Centos bootstrap OS image together with ISO and then package it into rpm. Since Fuel 8.0 we switched to Ubuntu bootstrap image usage  and CentOS one became deprecated, so in Fuel 9.0 we can freely remove it .
By removing fuel-bootstrap-image  we:
Remove CentOS bootstrap image usage from Fuel projects.
Currently we build Ubuntu bootstrap OS image on the master node using Fuel Agent. Although Fuel Agent does not support building Centos images we can implement such functionality.
We need to implement build image utilities for Centos and modify Fuel Agent build image manager method and probably input data driver so as to make it possible to use Fuel Agent to build Centos images.
We no longer need to deliver/update fuel-bootstrap-image package , this will simplify patching/update story, since we don’t need to rebuild this package on each changes in any dependent packages :
Changes should be reflected in documentation.
- ISO should pass QA acceptance criteria (SWARM % pass)
- User should not ba able to use CentOS bootstrap image
