Description of problem:
When using deployed-ceph with `--crush-hierarchy` parameter to the ceph deploy command, a file has to exist but should not be needed by default.

Version-Release number of selected component (if applicable):
RHOS-17.1-RHEL-9-20230525.n.1

How reproducible:
Deploy ceph with `--crush-hierarchy` parameter and without `--config` nor pre-created ceph.conf.


Actual results:

The ceph deployment will fail:

Expected results:

ceph.conf is not required if I don't want to provide one, so ceph-cli should not try to bind mount /home/ceph-admin/assimilate_ceph.conf which doesn't exist.
