Added .codecov.yml to support monorepo like structure to report cover…

[tallandroid]

Added .codecov.yml based on the flag support for https://docs.codecov.io/docs/flags. I have validated the configuration but cant test it with the original repo as I dont have the repo token :

Validation Output:

  "flags": {
    "projectA": {
      "paths": [
        "^engine-executor/src.*"
      ]
    },
    "projectB": {
      "paths": [
        "^python-toolbox/marvin_python_toolbox.*"
      ]
    }
  },
  "coverage": {
    "status": {
      "project": {
        "default": {
          "threshold": null,
          "target": 70.0
        },
        "engine-executor": {
          "flags": [
            "engine-executor"
          ],
          "target": 50.0
        },
        "python-toolbox": {
          "flags": [
            "python-toolbox"
          ],
          "target": 70.0
        }
      }
    }
  }
}

Could the repo owners help with testing the configuration

From the codecov report above, it still only get the python part. Not sure if it is because there is no code change?

[tallandroid]

Ok , so i have tried multiple configurations. The core problem was travis not uploading the configuration. Adding flags do help to segregate coverage between python and scala.

It can be found here : https://codecov.io/gh/tallandroid/incubator-marvin/branch/MARVIN-43

That being said, travis is executing build target for python toolbox twice for some reason by design. Ill go ahead and discard this PR for now.

Ill open a new PR for just reporting sbt coverage along with python coverage without the flags for now. But this needs to be fixed going forward.

Thanks for the investigation and discovery!
