kill stale test processes (zenserver, minio, nomad, consul) before and after CI test runs (#909)

Adds steps to the validate workflow on all platforms that kill any zenserver, minio, nomad, or consul processes launched from the build output directory. Runs before tests to clear stale processes from previous runs, and after tests (always, even on failure) to clean up.
