Add unit test cases for gpuagent

[mithun-pensando]

the test cases can be run by running make from the tests folder, it builds a test container and builds the go grpc client code and runs go test from inside the container. user needs to pass the IP of the server where gpuagent is running.
Sample test run output:

I guess these new go.mod & .sum files are needed for the go tests?

[mithun-pensando]

Yes
