Description of problem (please be detailed as possible and provide log
snippests):

The ceph-dencoder command doesn't like when we export CEPH_ARGS as required to run ceph [1] commands in ODF.

sh-5.1$ ceph-dencoder
-h for help
sh-5.1$ ceph status
sh-5.1$ export CEPH_ARGS='-c /var/lib/rook/openshift-storage/openshift-storage.config'ng conf_read_file)')
sh-5.1$ export CEPH_ARGS='-c /var/lib/rook/openshift-storage/openshift-storage.co
sh-5.1$ ceph-dencoder
unknown option '-c'
sh-5.1$ ceph status
cluster:
id: 841d721b-6d0e-436a-b69d-f85f9f9c2e89
health: HEALTH_OK
ion '-c'
sh-5.1$

Version of all relevant components (if applicable):
At least on:
ODF 4.14
ODF 4.15
Havent tested other versions..

Is there any workaround available to the best of your knowledge?
Yes, don't export CEPH_ARGS.

Rate from 1 - 5 the complexity of the scenario you performed that caused this
