Provide init.d / systemd examples

[robertoschwald]

To ease the demonizing of jmxproxybeat it would be good to add example file for it

jmxproxybeat.initd:

#!/bin/bash
#
# jmxproxybeat          jmxproxy shipper

Thanks @robertoschwald. I am sorry for the delay with my response. Thanks for your suggestion. I believe it would be great as documentation page to help people.

Once I finish migration to libbeat v5 I can update also documentation with your example! Again, thanks for your nice example.

[robertoschwald]

Updated the init.d script stop() routine, as it did not reliable stop the beat. Now it detects still running beats and performs a forced stop of all jmxproxybeat instances.

Thanks again @robertoschwald
