REVERTME :exclamation: FIXME: Workaround Unsigned MapR repos: Add `--force-yes` flag to all MapR package installs

Revert this once MapR Ubuntu repos have proper key signing for security reasons ;-)  :smile_cat:
Workaround for Ubuntu's SysV init script that exits with code 1 when Upstart exists for: start, restart
Set the host-specific attributes in Vagrantfile correctly for recipes: mapr::disksetup, mapr::hostname
Adding Vagrantfile fixes to cluster-wide node attributes

This was causing problems when running per-host commands like: `vagrant ssh mapr-NN`
Merge branch 'set-host-attributes-in-vagrant' into develop
Merge branch 'workaround-unsigned-apt-repo' into develop
