Provision: Script for linux to remove preinstalled software

Script to remove tier1's preinstalled software. Script itself includes
all information about the software that needs to be removed from tier2
before provision starts to run installations. When this script is run
for certain platform that platform needs to provision all removed
software back to tier2 template. So user needs to make sure that all
needed provision script are available when calling this removal-script.
Goal is to have vanilla os when provision don't need to remove any
software before installations. When this goal is reached this script
and script calls can be removed from provision.
