CC-2592: Full install issues running twice in a row

- use "rm -rf" instead of "rm" when deleting
/etc/apache2/sites-enabled/000-default

- append "include /etc/monit/conf.d/*" to /etc/monit/monitrc if
it's first time installing it.

- bypass python lib installation and patching if virtualenv
already exists
