We can't kill and restart osds because that will interfere with
the upgrade process. We can, however, thrash the layout by
tweaking osd weights and so on. This will exercise osd recovery
paths during the upgrade that aren't normally exercised (outside
of stress-split..which doesn't upgrade individual osds while they
are non-clean).

The previous method to get the watcher admin socket was fragile
and had started to fail after the recent changes to vstart ceph.conf.

Rearrange logic to make it easier to measure accumulation.
Instrument the boto request/response loop to count bytes in and out.
Accumulate byte counts in usage like structure.
Compare actual usage reported by ceph against local usage measured.
Report and assert if there are any short-comings.
Remove zone placement rule that was newly added at end: tests should be rerunable.
Nit: the logic to wait for "delete_obj" is not quite right.

rbd-ggate spawns a process responsible for the creation of ggate
device and forwarding I/O requests between the GEOM Gate kernel
subsystem and RADOS.
On FreeBSD it provides functionality similar to rbd-nbd on Linux.

There is some other random workload running (that creates pools)
while we upgrade and wait for healthy. Just disable the warning
for these tests.

If a class is no more referenced by any devices or crush rules,
it shall be considered as dead.
This patch makes Ceph automatically recycles those dead classes,
so user does not to explicitly call 'class rm', which is unsafe
and annoying.

The current version is broken. E.g., it should only remove a class
which is never referenced by any device.
Since we now create new classes automatically, we shall automatically
recycle dead classes too. So this command is definitely unuseful.
(Actually it is weird that we keep 'class rm' without keeping the
corresponding 'class create' command).
