this commit will ensure that any concurrency during the go build only happens across platforms, and no concurrent calls to go build or go install happen for a given platform.
the goal here is to reduce races between concurrent invocations of go build where package files are removed form the file system leading to "can't find import" errors.
refactor integration tests splitting out the kubernetes
cluster setup to just be in a script and making it the reponsibility
of the host/user/jenkins.
integration tests now run just like unit tests using "go test".
inital commit to convert release scripts to makefiles for improved maintenance.
now publishing to docker hub including manifest list support.
initial attempt at reworking the jenkinsfile to pipeline syntax.
