Add support to group problems view by the problem source

[gayanper]

Today then problems view shows all problems from different sources. For example you could see lot of problems in a java workspace. Problems from java LS, Sonar LS and Maven LS (redhat xml) all will be shown in the list. It would be nice if the problems can be grouped so it will be easy to focus on each problem type. Another alternative for grouping is add the same support into filtering which will also solve the above use-case.
