    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
