Log excerpts, setup details (before/after modifying the option names)

Description of problem:
Setting volume option "ssl.certificate-depth" to user-defined value triggers warnings about 

Version-Release number of selected component (if applicable):
3.7.11

How reproducible:
Given volume <vol>, execute "gluster volume set <vol> ssl.certificate-depth 1"

Actual results:
The option value is stored, but not correctly copied elsewhere ("namespace problem"), triggering the following warning (see attachment for context):
W [graph.c:357:_log_if_unknown_option] 0-webroot-client-<Number>: option 't
ransport.socket.ssl-cetificate-depth' is not recognized

NB it is not clear whether there's another side effect of this inconsistency (current setup with certificates fails, regardless of value for ssl.certificate-depth and ssl.cipher-list).

Expected results:
No warning.


Additional info:
The following changes get rid of the warning (resulting configuration is clean, but a test run still shows the same certificate errors, see bottom of attached file):
    sed -i 's|ssl-cert-depth|ssl-certificate-depth|g' rpc/rpc-transport/socket/src/socket.c xlators/mgmt/glusterd/src/glusterd-volume-set.c
    sed -i 's|ssl-cetificate-depth|ssl-certificate-depth|g' xlators/mgmt/glusterd/src/glusterd-volgen.c
