target uses.

This fixes the the following selinux error when using ceph-iscsi's
rbd-target-api daemon (rbd-target-gw has the same issue). They are
a result of the a python library, rtslib, which the daemons use.

In several places, such as common/numa.cc we call sched_setaffinity
which requires this permission.

We are using libudev and reading the udev db files because of that. We
need to allow ceph to access these files in the SELinux policy.

We hit a couple more SELinux denials when running ceph on RHEL8. The
dac_read_search change is related to a kernel change where it checks
dac_read_search before dac_override, now.

This adds selinux support for the ceph iscsi daemons under the ceph
github:
ceph-iscsi-config - rbd-target-gw
ceph-iscsi-cli - rbd-target-api
We use tcmu-runner, but that will go into the core policy to avoid
conflicts with gluster and distro bases.
This requires the patches:

The ceph-volume testing showed that the ceph daemons can run ldconfig in
a corner case when they are forbidden access to some files. This patch
allows ceph to execute ldconfig in Enforcing mode.

We currently create the ceph lock by an unconfined process (ceph-disk).
Unconfined processes inherit the context from the parrent directory.
This allows ceph daemons to access the files with context inherrited
from the parent directory (/var/lock | /run/lock).

We do suggest users to put their logs in /var/log/radosgw in the
documentation at times. We should also label that directory with
ceph_var_log_t so that ceph daemons can also write there.
The commit also updates the man page for this policy. This man page is
automatically generated by
* sepolicy manpage -p . -d ceph_t
and have not been reloaded in a while. Hence, it contains few more
changes than the new radosgw directory.

The SELinux man page was previously located in two places and the man
page that was supposed to be updated when rgw selinux changes were
proposed did not get updated properly. Fixing this by moving
selinux/ceph_selinux.8 to man/ceph_selinux.8. Also, populate EXTRA_DIST
with ceph_selinux.8.

The current SELinux policy does not cover radosgw daemon. This patch

We need to force single-core compilation of SELinux policy files in the
