lookup request, so we first fetch a lightweight list of contacts
and times modified, then we download any CardDAV Vcards we don't
have, or which has been updated.
Once we have the Vcards, we save them to disk as a file per VCard
which we can then search through when a lookup is required.
We cache the lookup results in memory for the running session
to avoid too many file searches.
