Opsgenie integration broken for generated GoCD pipelines (tubular)

[timmc-edx]

Our Opsgenie integration is broken for generated pipelines:

• sudo pip3 install ./tubular fails with an error about sudo wanting a password
• The Opsgenie calls don't have a --responders set -- see Fix GoCD opsgenie pipeline alerting (responders and integration) #1005 for details and broader fix

We'll want to copy the pattern used here:

SRE ticket for figuring out the tubular part, although I think we can just do this ourselves now that we've tested a fix on the security pipeline: https://2u-internal.atlassian.net/browse/GSRE-2762

See also #1005 for a different failure mode that becomes relevant after this one is fixed.

Blocked on getting the right python version installed for tubular.

Working now.
