[Bootstrap] Add additional packages installation support

This patch add a new bootstrap step which allows to install additional
distribution specific packages. The distribution type is retrieved via
the DISTRIB_ID value /etc/lsb-release, by using the lsb_release utility,
which is assumed to be present in the target system.
