combine all test plugins in to one

Do we need all these separate plugins or can live with one?
One problem here is that each of these plugins use ../src/CSCMap1.cc file and generate 
<tmp_path>/<pluginnameX>/../src/CSCMap1.o
so basically the output object file for all these are same which can cause problem while compiler with -j n.

If having separate plugins is required then we can do something like
<library name="CSCMap1" file="../src/CSCMap1.cc"/>

and then link it in each plugin but I would prefer to have one plugin.
