src/daemon: enforce ceph-{disk,volume} ulimit

The ceph-disk and ceph-volume commands perform badly in container when using the default max open files ulimit value (1048576). Setting this to 1024:4096 (soft:hard) solves the performance issue. Note that it won't by applyied to the ceph-osd process because we also enforce a specific value. Signed-off-by: Dimitri Savineau <[email protected]> (cherry picked from commit 64b9597)
