These changes add a new function, sw-update-headers, which runs a headless Chrome browser to scrape the required Authentication headers for checking in and stores them in Parameter Store. The check-in lambda then pulls these headers from the Parameter Store on invocation and uses them to (hopefully) check in successfully. Right now the sw-update-headers lambda is triggered every hour, but it could be improved to run on check-in failures or something. I had to fight a _lot_ with the correct Python/Selenium/Chromium versions on Lambda. This exact combination of Python 3.6 and the Chromedriver was the only one I could get to work. So we're stuck on 3.6 until this is resolved.
- Add the update headers function to the state machine when checkins fail. There's a potential for an endless loop here but I'll keep that in mind for later. - Fix hard-coded uid in Makefile - Reduce memory size for update headers fn - Move state machine JSON to a template file
