Use python3 for CSITs

- use python3 and pip3 in scripts
- update robot-framework-http library, so it can use python3
- update selenium2library, so it can use python3

Fixed merge conflict from cherry pick:
- prepare-csit.sh

Changed to github instead of gerrit-mirror, as the mirror is flakey and
broke one of the CSIT verify jobs.
