Bug #8753: USR1/USR2 signals during connection retry causes exit
https://projects.puppetlabs.com/issues/8753

Branch:
Affected mCollective version: 1.2.0
mcollectived seems to handle USR1 and USR2 signals (for reloading agents/logs)
badly if it's attempting to reconnect to a STOMP server at the same time.
If it's unable to connect to STOMP at startup and receives a signal then the
process exits abruptly. The following can be observed if running with
`daemonize = 0`:
<pre>
[root@xxx ~]# ruby /usr/sbin/mcollectived --pid=/var/run/mcollectived.pid
--config=/etc/mcollective/server.cfg
connect to stomp.labs.xxx.com failed: Connection refused - connect(2) will
retry(#0) in 5
connect to stomp.labs.xxx.com failed: Connection refused - connect(2) will
retry(#1) in 5
connect to stomp.labs.xxx.com failed: Connection refused - connect(2) will
retry(#2) in 5
/usr/libexec/mcollective/mcollective/connector/stomp.rb:128:in `connect': Could
not connect to Stomp Server: SIGUSR1 (RuntimeError)
from /usr/lib/ruby/site_ruby/1.8/mcollective/runner.rb:16:in
`initialize'
from /usr/sbin/mcollectived:57:in `new'
from /usr/sbin/mcollectived:57
</pre>
If it's able to connect to STOMP on startup, but subsequently loses connection
and receives a signal then the following is repeated in quick succession:
<pre>
transmit to stomp.labs.xxx.com failed: stopping only thread
note: use sleep to stop forever
transmit to stomp.labs.xxx.com failed: stopping only thread
note: use sleep to stop forever
transmit to stomp.labs.xxx.com failed: stopping only thread
note: use sleep to stop forever
</pre>
