Fix for TED issue.

TED has translation tasks that have new_subtitle_version set to a
version for the primary language.  We should ignore those for the
perform links.
Fix HTTP notifications

We were passing verify=False, but that doesn't seem to be a valid
option in the current API.  Use disable_ssl_certificate_validation
when creating the Http object instead.
Update integration repo
Added some more teams permission checks

I implement these for working on the TED api, but I'm not sure if we
will use them or not.  In any case, they might be helpful for the
future.
Send notifications to teams in more instances

This code is really annoying, I really want to refactor how it works.
See 2524.
Updating integration repo
Include language id in HTTP pings.
Merge branch 'staging' into editor-syncing
