Description of problem:
Consider the following setup with an Atomic Host
Atomic Host is registered to RH Satellite and is consuming content from Sat for upgrades. Now the user runs "docker run -it registry.access.redhat.com/rhel7" and tries to "yum install screen".  This is going to cause a 404.

Basic problem here is that in a Satellite the URL used for consuming yum content is different from url used for "atomic upgrade". However subscription manager has only one 'baseurl' entry. 


Sample rhsm.conf configuration for RHEL using satellite
"""
# Unified Entitlement Platform Configuration
[server]
# Server hostname:
hostname = .....
.....

[rhsm]
# Content base URL:
baseurl= https://sat-fqdn.com/pulp/repos/
.......

"""

Sample rhsm.conf configuration for RHELAH using satellite
"""
# Unified Entitlement Platform Configuration
[server]
# Server hostname:
hostname = .....
.....

[rhsm]
# Content base URL:
baseurl= https://sat-fqdn.com/pulp/ostree/web/
.......

"""

A clean approach here would be for subscription manager to have something like

"""
# Unified Entitlement Platform Configuration
[server]
# Server hostname:
hostname = .....
.....

[rhsm]
# Content base URL:
baseurl= https://sat-fqdn.com/pulp/repos

atomic_baseurl= https://sat-fqdn.com/pulp/ostree/web/
.......

""""


This subscirption manager can use atomic_baseurl when setting /etc/ostree/remotes.d/redhat.repo while using baseurl for yum.
