prepare_instance.sh can be re-run

Instead of failing (re-create symlin) or redoing long activities
(re-install ruby and rubygems), it skips those steps if
not necessary

Add gemspec for bosh agent.

This does not replace the Gemfile yet due to some remaining issues with
dependency selection by platform. I plan to use it to build the gem and
vendor it in the micro repo.

Monit starts colocated jobs in order

Monit loads the /var/vcap/monit/job/*.monitrc symlinks
and starts them in reverse alphabetic order.

The numerical prefix is 4 digits, which will allow for
the colocation of 10,000 jobs on the same VM. This is
called "Martin's Job Safety Number".
