Description of problem:
When using the 'gwcli' to create the iSCSI GW you must use the 'skipchecks=true' argument when creating the gateway using private kernel for RHEL 7.4 (3.10.0-823.el7). 

Section 9.2.2 of the Block Device Guide would require step 2 of 'configuring' to be as follows:

# create <iscsi_gw_name> <IP_addr_of_gw> skipchecks=true

The issue is that the kernel is based on 7.4 z stream and the check we are skipping checks for 7.5 devel kernel.

https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/3/html/block_device_guide/using_an_iscsi_gateway#configuring_the_iscsi_target_using_the_command_line_interface

Currently states:

# create <iscsi_gw_name> <IP_addr_of_gw>
