keep fetching descriptors, even when idle.
If set to 0, Tor will avoid fetching useless descriptors: flavors that it
is not using to build circuits, and authority certificates it does not
trust. When Tor hasn't built any application circuits, it will go idle,
and stop fetching descriptors. This option is useful if you're using a
tor client with an external parser that uses a full consensus.
