insights-client support bundle

Description of problem:
Though Insights data collection and upload of report is successful there are several error messages printed to STDOUT/STDERR. This is confusing and should not happen.

Version-Release number of selected component (if applicable):
Client: 3.1.1
Core: 3.0.200-1

How reproducible:
I found the problem in my lab environment. The issue is reproducible in an isolated environment where the insights-client is accessing Insights through a proxy.

The affected host is running as a libvirt-guest in an isolated network. Name resolution is only available for the internal zone 'private1'. To access the internet the host has to use a squid proxy running on a RHEL 8 machine. RHSM and insights-client are configured to use this proxy as described in KB 1583183 [Accessing Red Hat Insights Through a Firewall/Proxy](Accessing Red Hat Insights Through a Firewall/Proxy).

~~~
$ grep proxy /etc/rhsm/rhsm.conf
# an http proxy server to use
proxy_hostname = 192.168.100.2
# The scheme to use for the proxy when updating repo definitions, if needed
proxy_scheme = http
# port for http proxy server
proxy_port = 3128
# user name for authenticating to an http proxy, if needed
proxy_user =
# password for basic http proxy auth, if needed
proxy_password =
# host/domain suffix blacklist for proxy, if needed
no_proxy =

Steps to Reproduce:
1. Run `sudo insights-client --register` OR in case you're already registered `sudo insights-client`

Actual results:

~~~
$ sudo insights-client --register

Additional info:

Checking https://cloud.redhat.com/insights/ I can see that the report has been uploaded successful. I think the error described should not happen. All communication should happen using the configured proxy.

I ran `sudo insights-client --support` to gather additional information and attached the archive to this bugzilla.
