Merge pull request #4 from mbautin/fix_dep_on_clearstorydata-monit

back and forth, always sending notifications to daemons and forcing them
to restart.
Update cloudera cookbook dependency and fix clearstorydata-monit dependency

Also remove comment from the Tachyon user because it changes the comment
for the spark user when they are the same.
Use shellescape instead of inspect
