Comment 0 for bug 1884824

Brief Description
-----------------
A single use can't build stx docker images in parallel. When two jenkins jobs tried to invoke
build-stx-images.sh in parallel, building in different environments and on different branches, on failed with ...

docker: Error response from daemon: Conflict. The container name "/jenkins_update_img" is already in use by container "1932b698d2009848fd9f8912467d9c637c72b9bd45d212ac10f7b0aec2f1cebd". You have to remove (or rename) that container to be able to reuse that name.

The issue is the use of "${USER}_update_img" as a name for a temporary image. It is not unique when a single user is building in parallel. Perhaps add the pid to the image name like this ..."${USER}_$$_update_img" ... to make it unique.

Severity
--------
Major. Random image build failures for jenkins, or other power users

Steps to Reproduce
------------------
A single user sets up two independent build environments on the same system.
Both run build-stx-images.sh in parallel.

Expected Behavior
------------------
images build

Actual Behavior
----------------
One og the builds fails sporadically.

Reproducibility
---------------
