build-unit-test-docker: split docker stages into invocations

Rather than a single large Dockerfile, split each stage into its
own Dockerfile with its own invocation.  This is in preparation
for building the docker stages in parallel.

Since multiple invocations of this script could be running in
parallel, possibly with different content, this requires creating
well-named tags for each stage.  Create these tags as a combination
of the current date and the content that went into the stage
Dockerfile.  The date is used so that we can refresh the base
image more regularly.
