Show error message when failed to create resource

[baelen-git]

See the output of the command below

❯ isctl --config ~/.isctl-ocp2.yaml apply -f vnic_ethif.yaml   
INFO[0000] Performing create operation on new MO (Name: eth0, ClassId: vnic.EthIf) 
FATA[0003] Error while applying MOs: Error executing operation: 400 Bad Request 

I would like to know the reason of the failed API POST. You can get this by enabling verbose mode.

❯ isctl --config ~/.isctl-ocp2.yaml apply -f vnic_ethif.yaml   -v
INFO[0000] Performing create operation on new MO (Name: eth0, ClassId: vnic.EthIf) 
.....
{"code":"InvalidRequest","message":"The request body contains the 'SpVnics' relationship, which is read-only. Do not include read-only relationships in the request body","messageId":"barcelona_request_cannot_modify_read_only_relationships","messageParams":{"1":"SpVnics"},"traceId":"zHDFd14jBvtLVtzIN-wrgUQ1Fo3SG2PVj4KnkT2uMOyYnM2ku0n1Kg=="}
FATA[0002] Error while applying MOs: Error executing operation: 400 Bad Request 

Please grep the message from the response when there is an error and show that message (without enabling verbose mode)
