Resolves: RHEL-15137
Appropriate commands are added to tuned-adm as well.
`get_instances`: Retrieves a list of active instances of a given
plugin or all active instances.
`instance_get_devices`: Retrieves a list of devices assigned
to a given instance.
Also added the -i and --ignore-missing options to the tuned-adm manual page.

The new profile sets the intel_acpi driver to passive mode to
be able to set the standard acpi governors (ondemand/userspace)
and provides more flexibility on the C-states, as it is exposed
as a new variable.

The 'D' is now capital to clarify pronunciation.
DBus service name is kept as '/Tuned' not to break
backward compatibility.
This will also need update of downstream tests
which rely on the specific output strings containing
the name.

Profile which tunes down I/O activity to the serial console by reducing the
printk value. This should make the serial console more responsive.
This profile is intended to be used as an overlay on other
profiles (e.g. throughput-performance profile), example:
# tuned-adm profile throughput-performance optimize-serial-console
Also minor fixes to the man page quoting.

Intel's new Speed Select Technology (SST) is a process power management
technology introduced by Intel that allows for throughput and per-core
performance configurations and optimizations such as allowing for
prioritization of workloads on specific cores by sacrificing performance
on other cores.
Intel has released several CascadeLake processors, commonly referred to
as CascadeLake-N, with this technology and will introduce further SST
related technologies in the next few years.
These new technologies require the disabling of the intel-pstate driver
configuration in tuned as it may interfere with the user chosen per-core
configurations of SST.
Add a new SST profile to tuned for general use.

The reapply_sysctl functionality was originally added to address
rhbz#1302953, which was about Tuned overriding sysctl config files
from /etc, which was deemed undesirable. The bug said nothing about
sysctl config files from /usr/lib/sysctl.d, /lib/sysctl.d or
/usr/local/lib/sysctl.d.
Having sysctl configs from /usr override Tuned profiles causes
problems (rhbz#1759597). Also, it seems reasonable for Tuned profiles
to override sysctl configs from /usr - a Tuned profile is often
explicitly chosen by the user, whereas sysctl configs from /usr are
provided by system packages whether the user wants them or not.
Also, in RHEL-6, tuned used to ignore sysctl config files from /usr,
as far as I can tell.

As discussed in rhbz#1672213, the sap-hana-vmware profile is not needed
anymore and it only confuses users. Let's drop it.

Since commit cd4943bdbf, it is recommended to use ${i:PROFILE_DIR}
in paths to scripts, in order to make the paths absolute. It's not
required (yet) though.

The manpage already exists, but it's empty. So, this commit actually
