Update README/docs related to contributing and level of service

* NSIDC user services has no capacity to officially support `iceflow` until at
least August. In the meantime, we want to respond to community-submitted issues
and PRs as time allows, but want to still make it clear that this is not a
fully-supported product.

* Move `CONTRIBUTING.md` to doc/ as a new page in RTD and reference it in the
"Level of Support" section.
