Add TunedCustomProfile parameter and HCI Ceph filestore environment

Add TunedCustomProfile parameter which may contain a string in
INI format describing a custom tuned profile. Also provide a new
environment file for users of hypercoverged Ceph deployments
using the Ceph filestore storage backened. The tuned profile is
based on heavy I/O load testing. The provided environment file
creates /etc/tuned/ceph-filestore-osd-hci/tuned.conf whose
content is the following and sets this tuned profile to be active.

[main]
summary=ceph-osd Filestore tuned profile
include=throughput-performance
[sysctl]
vm.dirty_ratio = 10
vm.dirty_background_ratio = 3
[sysfs]
/sys/kernel/mm/ksm/run=0

Add new TunedCustomProfile parameter which may contain a string
in INI format describing a custom tuned profile. Also provide a
new environment file for users of hypercoverged Ceph deployments
using the Ceph filestore storage backened. The tuned profile is
based on heavy I/O load testing. The provided environment file
creates /etc/tuned/ceph-filestore-osd-hci/tuned.conf and sets
this tuned profile to be active. Not intended for use with Ceph
bluestore.
fixes:

CephOSD/Compute nodes crash under memory pressure unless custom tuned profile is used
(`bug 1800232 <https://bugs.launchpad.net/tripleo/+bug/1800232>`__).
