Add config file for ambari url properties

[spolex]

I've been testing this script in azure cloud and it works. I've added some variables in order to improve security and simplicity.

Thanks a lot for this resource!

Hi @spolex, I missed this request. Sorry, I'm not really sure about this. The path may be something like /etc/ambari-shell-script.properties or something similar for using it in a service script or from any path (instead of pwd). Maybe it's a better aprox for nagios plugins too, to prevent some repeated stuff. Thanks for the testing, and let me think a little bit about it.

Regards.

Hi @CesarCapillas,
It''s up to you. Depends on the main goal. One different solution could be parametrize in config file the path.
