ceph_manager: workaround for 6116

This is an annoying race, we really should delay going
clean until the backfill peer has acknoledged the clean
info, but we currently don't.  In order to prevent this
bug from messing up the nightlies, we'll delay killing
the peer for 20s to make it likely that the backfill
peer has gotten the clean info.

Workaround: #6116

rbd_fsx: do not exceed 250GB for fsx image

This breaks on 32-bit architectures because fsx can't allocate the
in-memory buffer or hit some other limit.  500MG also seems to run out of
memory (tho it at least does not segfault).

Fixes: #6576

Use worker httpd instead of prefork (like ubuntu) on rpm distros.

Ubuntu's default apache uses worker instead of prefork like rpm
based distro's. If rpm use httpd.worker instead of httpd so that
the -X behavior will not be blocked by a single request.
