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.
