Updates for Python 3 compatibility

[taldcroft]

This moves Ska watch processing into a new skawatch3 namespace in data and share to make this a softer transition.

The actual Py3 changes were expected and trivial.

I ended up making more changes than expected to get tests to pass. I don't think they were still passing on the Py2 side at this point, but I didn't actually check.

Testing

• [x] Passes unit tests
• [x] Functional tests
  • Running skawatch.py and hourly_watch.py locally in repo gives expected results.
  • Going to install this as a cron job and run as aldcroft for a bit to validate.

In task schedule

Ran as per cron job schedule:

/proj/sot/ska3/flight/bin/skare task_schedule3.pl -config /proj/sot/ska3/flight/data/skawatch3/task_schedule_hourly.cfg
/proj/sot/ska3/flight/bin/skare task_schedule3.pl -config /proj/sot/ska3/flight/data/skawatch3/task_schedule_daily.cfg

Outputs:

• https://cxc.harvard.edu/mta/ASPECT/skawatch3/2020155/index.html
• https://cxc.cfa.harvard.edu/mta/ASPECT/skawatch3/hourly/status/index.html

To do:

• [x] Change alert emails from aldcroft to aca.

Thanks for the work on this @taldcroft ! Looking good. Are you running it manually now as you are testing? I was wondering about the cadence of the warnings showing up in my inbox.

I have been running manually and via cron jobs. I'll update the aspect cron page, but this is the current setup as me on kady:

## Skawatch
40 10 * * * /proj/sot/ska3/flight/bin/skare task_schedule3.pl -config /proj/sot/ska3/flight/data/skawatch3/task_schedule_daily.cfg

# Hourly skawatch/jobwatch
5 */2 * * * /proj/sot/ska3/flight/bin/skare task_schedule3.pl -config /proj/sot/ska3/flight/data/skawatch3/task_schedule_hourly.cfg

I disabled the Ska2 hourly watch to stop the hourly spamming. The Ska3 hourly seems to be giving good results now.

After we have let this soak for a few days my plan would be to:

• [x] Remove all skawatch Ska2 cron jobs
• [x] Set up redundant skawatch3 Ska3 cron jobs on coot
• [x] Remove /proj/sot/ska/data/skawatch and /proj/sot/ska/share/skawatch to avoid future confusion. I don't see too much archival value in the current contents.
