common: fix for broken rbdmap parameter parsing

common: fix for broken rbdmap parameter parsing

This improves the broken parameter parsing discussed in #36327

Test expression for the parsing function:

PARAMS="options='lock_on_read,queue_depth=1024',id=archiv,keyring=/etc/ceph/ceph.client.archiv.keyring"
echo -e " ORIGINAL PARAM: >>>$PARAMS<<<\nCONVERTED PARAM: >>>$(create_cmd_params "$PARAMS")<<<"

PARAMS="id=archiv,keyring=/etc/ceph/ceph.client.archiv.keyring,options='lock_on_read,queue_depth=1024'"
echo -e " ORIGINAL PARAM: >>>$PARAMS<<<\nCONVERTED PARAM: >>>$(create_cmd_params "$PARAMS")<<<"

PARAMS=""
echo -e " ORIGINAL PARAM: >>>$PARAMS<<<\nCONVERTED PARAM: >>>$(create_cmd_params "$PARAMS")<<<"

PARAMS=",keyring=/etc/ceph/ceph.client.archiv.keyring,options='lock_on_read,queue_depth=1024',id=archiv,"
echo -e " ORIGINAL PARAM: >>>$PARAMS<<<\nCONVERTED PARAM: >>>$(create_cmd_params "$PARAMS")<<<"

PARAMS="'keyring'=/etc/ceph/ceph.client.archiv.keyring,options='lock_on_read,queue_depth=1024',id=archiv,"
echo -e " ORIGINAL PARAM: >>>$PARAMS<<<\nCONVERTED PARAM: >>>$(create_cmd_params "$PARAMS")<<<"

PARAMS="--keyring=/etc/ceph/ceph.client.archiv.keyring,options='lock_on_read,queue_depth=1024',id=archiv, # a comment"
echo -e " ORIGINAL PARAM: >>>$PARAMS<<<\nCONVERTED PARAM: >>>$(create_cmd_params "$PARAMS")<<<"
