Issues when running make test target locally

[sfc-gh-eraigosa]

We should make the local desktop testing for this project easier. Currently we have to make with the following command locally, unless you clone the project perfectly:

USE_CONTAINER=true GH_USER=HewlettPackard GH_REPO=oneview-golang make test

Lets make using docker to build this project the default, so that requirements will now be:

• docker
• make

No need to have golang even installed. This should remove the requirement for USE_CONTAINER option, but we should still have the option so that the setting USE_CONTAINER=false is possible under travis builds, where we don't have docker.

If we always build in docker then we can assume that GH_USER can always be HewlettPackard and GH_REPO=oneview-golang can always be oneview-golang. This also improves local testing before submits.

Lets also fix how we call docker to include -e GH_REPO and -e GH_USER in the Makefile.
