Refactor the acceptance-test stage scripts

[yongja79]

Currently acceptance-test-stage.sh scripts builds a container that calls either make test-pipeline-e2e or make kind-e2e-test setting various environment variables that then can be called within the container. These make files are in each of the 3 operator repos

make test-pipeline-e2e and make kind-e2e-test then call the e2e-ocp.sh and e2e-kind.sh scripts respectively passing in even more variables. These scripts are in the common operators repo.

We should call e2e-ocp.sh and e2e-kind.shdirectly bypassing make as its unnecessary.

At the same time some cleanup of what variables are used can be done as several are passed in that are no longer used (docker variables for example)
