[PATCH v7 08/16] fetch: refactor calculation of remote list

[Jeff Hostetler <git@jeffhostetler.com>]

From: Jonathan Tan <jonathantanmy@google.com>

Separate out the calculation of remotes to be fetched from and the
actual fetching. This will allow us to include an additional step before
the actual fetching in a subsequent commit.
