This patch wraps image build procedure into try-except-finally and appends some cleaning actions into finally section. If something goes wrong during image building, build environment will be cleaned up. 1) Stop running processes inside image chroot 2) Umount image chroot 3) Detach loop devices 4) Remove temporary files Closes-Bug: #1451817 Partially implements: blueprint ibp-build-ubuntu-images Change-Id: I7a7abf46f93fad3a3343dcf320781beec42f44bd
