Description of problem:
When registering with `subscription-manager register`, "--name" option seems to be ignored.


Version-Release number of selected component (if applicable):
Satellite: satellite-6.3.0-19.0.beta.el7sat.noarch
Client: python-rhsm-1.19.9-1.el7.x86_64
        subscription-manager-1.19.21-1.el7.x86_64


How reproducible:
always on my setup


Steps to Reproduce:
1. # subscription-manager register --activationkey ActivationKey --org 'Default_Organization' --name "Our database server"
2. Check on Satellite resulting name


Actual results:
[root@client ~]# hostname
client.example.com
[root@client ~]# yum upgrade \*subscription\* \*rhsm\*

Name is also not present in any fact:

[root@sat630 ~]# hammer -u admin -p changeme host facts --id 31 | grep -e client -e database
uname::nodename                               | client.example.com

network::fqdn                                 | client.example.com


Expected results:
Systems should be registered with specified name or at least name should be present in some of its metadata
