qa/tasks/ceph.conf: do not warn on TOO_FEW_OSDS

Signed-off-by: Sage Weil <sage@redhat.com>
(cherry picked from commit 0483c1c3e7ffdfa6a6f65c5ef000c45d2f096428)

qa/tasks/ceph.py: move methods from teuthology.git into ceph.py directly; support mon bind * options

Having these live in teuthology.git is silly, since they are only consumed
by the ceph task, and it is hard to revise the behavior.

Revise the behavior by adding mon_bind_* options.

ceph.spec.in: fix Cython package dependency for Fedora

Fedora distros do not have python3?-Cython packages, but they do have
python3-Cython ones. Fix the BuildRequires so that we only use the

install-deps.sh: use latest setuptools

this change reverts "install-deps.sh: workaround setuptools' dependency on six"

This reverts commit 30ce5e55460e333e1240704112a16fae68b3325f.

tl;dr: this change addresses the failures of "make check" runs on arm64
builders when they try to build `mgr-dashboard-test-venv` target.

long story: without this change, we will fail to pull in
setuptools >= 36, and as a result pip will fail to import
`setuptools.build_meta` in `pip/_vendor/pep517/_in_process.py`. and will
a `BackendUnavailable` exception thrown by `_call_hook()` in
`pip/_vendor/pep517/wrappers.py`. since the issue addressed by 30ce5e55
has been addressed since setuptools >= 36.0.1, we should be safe to
upgrade to the latest setuptools now.
