Description of problem:
After running some tests I wanted to submit the results with `hwcert-backend submit` but I only get a Error[111] "Connection refused"

Version-Release number of selected component (if applicable):
hwcert-client_14.6-57.el6

How reproducible:
Always

Steps to Reproduce:
1. Install RHEL, hwcert 
2. Set the environment variables for the proxies. In my case its:
export http_proxy="http://172.25.159.7:81"
export https_proxy="http://172.25.159.7:81"

3. run some tests and then do a `hwcert-backend submit`

Actual results:
The submit tasks asks first time if it should create a new cert or add to an existing. Then it asks for User-ID and password. After everything is entered, then you get the message "Could not submit results" because connection is refused.

Expected results:
Submit works.

Additional info:
I did an 'strace hwcert-backend submit` and the last lines show, that instead of honoring the proxy settings the process wants to establish a direct connection to  209.132.183.70 (which is hardware.redhat.com).

exit_group(0)                           = ?

Note: If the https_proxy is not set correctly you won't even be able to enter the User-ID. So I assume that the proxy settings are right, but it looks like that the central submit function doesn't care about proxy settings.
