Fetch users from Phabricator to link to issues

We fetch the users from Phabricator based on their Phabricator ID. If
a user with the same username exists and is a member of the project,
we set them as assignee or author.

When a user is applicable, we also cache it in Redis so we don't have
to perform the request again for the same phid.
