OC PhySim deployment: log bash script commands

Also, don't use "set -x" debugging for oc login command:
ci-scripts/cls_cmd.py:242 sets BASH_XTRACEFD=1, which makes that all
"set -x" output is in stdout, leading to a redirect to the file into
which we redirect. This would lead to the following error with
unsuccessfull oc login:

  error: You are not a member of project "****-core-for-ci-ran".
  Error from server (Forbidden): imagestreams.image.openshift.io "oai-physim"
  is forbidden: User "system:anonymous" cannot get resource "imagestreams" in
  API group "image.openshift.io" in the namespace "****-ran"
