The 'force' parameter of os-brick's disconnect_volume() method allows
callers to ignore flushing errors and ensure that devices are being
removed from the host.
We should use force=True when we are going to delete an instance to
avoid leaving leftover devices connected to the compute host which
could then potentially be reused to map to volumes to an instance that
should not have access to those volumes.
We can use force=True even when disconnecting a volume that will not be
deleted on termination because os-brick will always attempt to flush
and disconnect gracefully before forcefully removing devices.

Take the opportunity to clean up the docs quite a bit, ultimately
combining two disparate guides on the scheduler into one.

Use the formatting established in the style guide. There's a lot of
out-of-date information in here, but that's a battle for another day.

This adds the "compute:servers:resize:cross_cell" policy
rule which is now used in the API to determine if a resize
or cold migrate operation can be performed across cells.
The check in the API is based on:
- The policy check passing for the request.
- The minimum nova-compute service version being high
enough across all cells to perform a cross-cell resize.
If either of those conditions fail a traditional same-cell
resize will be performed.
A docs stub is added here and will be fleshed out in an
upcoming patch.
Implements blueprint cross-cell-resize

As discussed in the mailing list [1] since cells v1
has been deprecated since Pike and the biggest user
of it (CERN as far as we know) moved to cells v2
in Queens, we can start rolling back the cells v1
specific documentation to avoid confusing people
new to nova about what cells is and making them
understand there was an optional v1.
There are still a few mentions of cells v1 left in
here for things like adding a new cell which need
to be re-written and for that I've left a todo.
Users can still get at cells v1 specific docs from
published stable branches and/or rebuilding the
docs from before this change.
