Doc Text:
.Ceph ceph-ansible now installs the gwcli command during iscsi-gw install Previously, when using Ansible playbooks from `ceph-ansible` to configure an iSCSI target, the `gwcli` command needed to verify the installation was not available. This was because the `ceph-iscsi-cli` package, which provides the `gwcli` command, was not included as a part of the install for the Ansible playbooks. With this update to {product}, the Ansible playbooks now install the `ceph-iscsi-cli` package as a part of iSCSI target configuration.

Description jquinn 2018-07-18 13:35:24 UTC 
Description of problem:

Following our iscsi target installation steps that are documented here [1], after running the playbook the user should then verify that gwcli has been installed.  The gwcli command is not available following the install.  

I have tested with the following ceph-ansible versions and get the same results. 

Old package: ceph-ansible-3.0.14-1.el7cp.noarch
New package: ceph-ansible-3.0.39-1.el7cp.noarch


To install the gwcli I had to use the manual steps below.  

1. Install ceph-iscsi-cli  

[root@vm250-194 ~]# yum -y install ceph-iscsi-cli

2. Try to run gwcli and it fails. 

[root@vm250-194 ~]# gwcli
Unable to access the configuration object : REST API failure, code : 500
GatewayError: 

3. Need to enable and start the rbd-target-api service for the gwcli to work

[root@vm250-194 ~]# systemctl enable rbd-target-api
[root@vm250-194 ~]# systemctl start rbd-target-api
[root@vm250-194 ~]# systemctl status rbd-target-api
