remove old erzurumi ActiveMQ monitoring

check_stomp.pl etc, ancient monitoring for
ActiveMQ on erzurumi, back in RT #703 it
already got fixed, so existed before that

erzurumi is decom'ed, get rid of all the
remnants, remove the monitoring script
and the package for it as well as the check
command

completes "decom erzurumi" and removes
unneeded stuff from monitoring host

per JeffG. this is now monitored via NSCA
from inside frack..
