Remove test/systemtests/cfg.json so that it will be ignored

[vhosakot]

To run the Contiv k8s system tests, before running make k8s-test, we must first run scripts/python/createcfg.py (https://github.com/contiv/netplugin/blob/master/Makefile#L172). scripts/python/createcfg.py creates test/systemtests/cfg.json in https://github.com/contiv/netplugin/blob/master/scripts/python/createcfg.py#L77-L80.

But, since test/systemtests/cfg.json already exists in https://github.com/contiv/netplugin/blob/master/test/systemtests/cfg.json, . gitignore does not ignore it in https://github.com/contiv/netplugin/blob/master/.gitignore#L63 as git does not ignore a file already present in the repo. Due to this issue, contributors have unnecessarily committed test/systemtests/cfg.json into the netplugin repo by mistake (https://github.com/contiv/netplugin/commits/master/test/systemtests/cfg.json).

Hence, removing test/systemtests/cfg.json so that it will be ignored by . gitignore.

@dseevr @rchirakk @gaurav-dalvi - this got merged before I corrected the reference to netplugin/systemtests/cfg.json in the documentation in https://github.com/contiv/netplugin/blob/master/test/systemtests/How-to-Run.md. I'll submit a separate PR to correct the documentation and also add cfg.json.example as a sample for the user.
