Revert "Improve LVS check for Elasticsearch"

This isn't quite what I wanted. This is the icinga check which is checking
the overall cluster status. While we could be smarter there caring about
node-level status is overkill (compare to every other definition above this)

What I want to do is adjust the RunCommands in lvs' configuration.pp
to do something along the lines of what I attempted here.

This reverts commit 73c53dbaae87ace8222dfa70d23fd792886f8490.
