Python 3: Convert OPI scripts

[DominicOram]

As a developer I would like everything to be run on Python 3, this includes the scripts running in OPIs in the GUI. These scripts run in Jython and as of the time of writing there is no Jython 3 support (jython/jython3#36)

Acceptance Criteria

• OPI scripts are being run in python 3

Calling this impeded on a jython 3

[Kevin-Woods-Tessella]

I am not sure it is appropriate to label this ticket as impeded. An impediment is something that we ourselves can remove or influence someone to remove it on our behalf. If there is no prospect of removing the impediment in a timely manner, then it might as well return to the backlog.

What can we do to remove this particular obstacle? Can we resolve the Jython 3 issue ourselves, or do we have to wait for the maintainers of Jython to resolve it? I suspect it is the latter (i.e. the resolution is outside of our control and we can't influence it). We could set a reminder to check every few months to see if Jython-3 is available.

Ok, I wanted to put a label on it so that it was obvious that we couldn't pick it up easily, if ever. I'll remove the label.
