qa/suites/krbd: run unmap subsuite with msgr1 only

pre-single-major.yaml kernel doesn't have any of the monitor client
fixes that came in 4.6.  If the connection is closed, it closes the
session and retries only after 10 seconds.  On top of that, there is
nothing to prevent it from picking the same monitor when reconnecting.
This means that when given both v1 and v2 ports (which look like two
different monitors), it is susceptible to mount_timeout (60 seconds):

  $ sudo rbd map img
  rbd: sysfs write failed
  In some cases useful info is found in syslog - try "dmesg | tail".
  rbd: map failed: (5) Input/output error

Unlike newer kernels that return ETIMEDOUT, it returns EIO.

Newer kernels are much more aggressive about retries and will pick
a different monitor when reconnecting, hence they are always able to
establish the session in time.

ceph-backport.sh: add deprecation warning

The script is not maintained in the stable versions of Ceph.

This commit is not a cherry-pick from master, because the script is maintained
in master. It is unmaintained only in the stable versions, like "nautilus".

Also add a --version option which, in this case, will also indicate to the
user that this is an outdated, deprecated version of the script.

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
python3_version_nodots based version string for RHEL.

ceph.spec.in: s/pkgversion/version_nodots/

`python3_pkgversion` is now defined as 3, while we don't have packages
like python3-Cython yet in EPEL7. but we do have `python36-Cython`. so
let's use `python3_version_nodots` instead.
