Aali/ops 2209 upgrade sandbox mongo role

This is needed because there is a race condition between the stop and
start of supervisor.  The stop will not wait for all child process to
have shutdown by design because this behavior is needed for lms workers.

This means that when we try to do a stop and start together, and the first process
has not fully stopped, we get a failure in the startup of the second process.

There is no obvious way to deal with this in systemd so dealing with it here
instead.

This is needed so that we can properly build devstacks without passing in any other config.

WIP: script to make API call to get cache hit rate

Include the Environment-Deployment when announcing an AMI build

Otherwise, we see 3 edxapp AMI builds per gocd pipeline, but have
no idea which one is which.  Similar issue for IDAs where you get at
least 2 AMIs.

We get S3 timeouts a few times a week

Retry if we can't get to github.

We sometimes can't get to github because of intermittent network issues. We should
try a few times before we declare it a failure.
