Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1984400

Description of problem:

If we have a proxy set in Administer -> Settings -> General -> 'HTTP proxy' then capsule installation/upgrade fails because Satellite is not able to connect to capsule through proxy. In this scenario, the solution is to either remove the proxy or add the capsule in 'HTTP proxy except hosts' list.

Version-Release number of selected component (if applicable):
Satellite 6.x

How reproducible:
Always

Steps to Reproduce:
1. Set the proxy in Administer -> Settings -> General -> 'HTTP proxy'
2. Proxy should not be configured for internal routing
3. Try installing or upgrade the existing capsule.

Actual results:
Installation or upgrade fails.

Expected results:

We should add the capsule FQDN in 'HTTP proxy except hosts' automatically at the time of certificate generation on the Satellite or in some other way to prevent such issues.
