The "ubuntu" target had a post-install 99-autoremove task that removed unnecessary dependency packages, but the "ubuntu-minimal" target does not. This patch moves the 99-autoremove post-install task from the "ubuntu" target to the "ubuntu-common" target so that both will run an autoremove at the end of the image build. For the Octavia amphora image, this saved about 1GB in the image by removing build only package dependencies. Closes-Bug: #2012406 Change-Id: I4592e3bd502045fa89203c075d3ea8f632e77177
