Introduce a new "logging_syslog_can_network" boolean
...
and make the net_admin capability as well as all
corenetwork permissions previously granted
to the syslog daemon conditional upon such boolean
being true.

container: rework capabilities
...
Rework (primarily) non-namespaced capabilities. These accesses are
leftovers from earlier policy versions before the container module was
introduced that are most likely too coarse for most container
applications.
Put all non-namespaced capability accesses for containers behind
tunables, borrowing ideas from container-selinux. For the more
privileged capabilities (sysadmin, mknod), add a tunable to control both
namespaced and non-namespaced access to these operations.

Add label and interfaces for kernel PSI files
...
The pressure stall information (PSI) special files in /proc/pressure
currently don't have a separate file context, and so default to proc_t.
Since users need read/write permissions to those files to use PSI, and
handing out blanket permissions to proc_t is strongly discouraged,
introduce a new proc_psi_t label, as well as interfaces for it.

The pulseaudio daemon and client do not normally need to use
...
the network for most computer systems that need to play and
record audio.
So, network access by pulseaudio should normally be restricted.
This patch restricts all network access by using tunable policy
and a new boolean to control it.
