Deal with old closed github issues [2d]

[marcboscher]

We currently get all issues/tasks, even those closed. This can amount to a lot of items for large projects, even though most of them may never change again.

We need to get closed items to close corresponding item in other service

We could get closed items that have been modified within a certain time span, say 30 days

See analysis notes: https://docs.google.com/a/crosscheck.io/document/d/1UYvxjJAXNyX0dp_hQ5m-ijL95T8vXGBHGhfy0wFy5PQ/edit#

Do this in a branch as it will disruptive

[marcboscher]

Only ask for open github issues. When iterate through asana items, looking up github items by github id, if don't find github item, assume it means its closed.

could also lookup the individual github issue in this case to find out more.

issue: can still get comments and changes (labels, milestones) on closed issues. how will we update asana in this case?
