cache issue data and other objects

[dpocock]

Some objects should be cached to reduce the number of hits on the Github API

e.g. if we start looking up user records in order to put the issue reporter email address in the VTODO then we should cache them because people change their email addresses very rarely

The Beaker project may be useful, it is already packaged:

How about using redis for this ?
