Filter service call list in rqt_service_caller

It would be great if rqt_service_caller would not always list all available service calls (including all the logging related ones), but just specific ones. One could filter them, e.g. with a regexp, or via selecting a specific namespace.

My current, somewhat unsatisfactory workaround is to remap the name of the service I am interested in, so it appears first in the alphabetically ordered dropdown menu.

That sounds like a good improvement. Please consider to contribute a pull request which adds such a filter to the plugin.
