Set up a cron job to run benchmarks

[ericsnowcurrently]

This is an aggregate issue. Each sub-task will be done separately:

• Use a dedicated ssh key tools#31
• [portal] add jobs.py upload tools#57
• set up a GitHub bot user (faster-cpython-bot, faster.cpython@gmail.com)
• [portal] Add the jobs.py wait command tools#60
• fixes for running as a bot user
• Add support for a weekly benchmarking cron job tools#61
• add a cron job (on portal host or via GH action)

I'm tabling the rest of this work until it's more clear what needs to be done. This will likely be after faster-cpython/tools#33 is resolved.

I ended up needing the upload command anyway.

I set up the cron job today (to run every Sunday).

I'll close this next week, once we've verified that the cron job ran correctly.

@ericsnowcurrently: Can this be closed?

Yep. 🙂
