We perform almost the same activities prior calling createBootstrapIso
function like we do that in phase executor, also image build command
now is techically outdated since it doesn't work because it fails with
"phase document was not found" error. This patch removes unnecessary
functions like GenerateBootstrapIso and runs image build command in
a phase way. Test coverage increases slightly (by 0.2%) by removing
partially duplicating code which was not tested properly. Minor bug
fixes included.
