Enable autostart in osbash
This change enables autostart functionality for osbash. activate_autostart is called by a minimal script written by preseed/kickstart files (if configured). It creates (and grants sudo privileges to) the osbash user if that has not been done by preseed/kickstart. It uses template-osbashauto to generate /etc/init.d/osbashauto and configures the system to run the script immediately and during every subsequent system boot. osbashauto iterates over all files in the autostart directory (in the VirtualBox shared folder; filled by osbash from the host side) and executes them as the osbash user. It writes its log files into the log directory in the shared folder. Partial-Bug: 1312764 Implements: blueprint openstack-training-labs Change-Id: I0394c5ea4e3f75a9d9bee30d119e047a762e86ce
