@deepak07dbz can you check why the Github actions for build, test are failing - and then update them?

Please add details on testing - commands to show the multus pod working etc.

@deepak07dbz The GitHub actions have been updated in the master branch - e.g. they are passing on this PR #5
They may need further update e.g. to use new version of golang etc.
