Description of problem:

Syncing of any (new) repository does not work. Log file /var/log/pulp/pulp.log contains message "[Errno 110] Connection timed out", see below for full log.
It seems to me that pulp is ignoring http proxy settings (Katello server is without direct connection to Internet).

Distributor ID: RedHatEnterpriseServer
Description:    Red Hat Enterprise Linux Server release 6.4 (Santiago)
Release:        6.4
Codename:       Santiago


How reproducible:

1) Configure Katello server to use http proxy (no direct connection to Internet)
2) Create new product and repository
3) Sync new repository

Steps to Reproduce:

1. 
# katello-configure --proxy-url=http://myproxy --proxy-port=3128

# katello-configure -c
org_name = GPECZ
proxy_url = http://myproxy
proxy_port = 3128

2.
 Create new custom product and repository
 Example:
 Product Name: Fedora
 Repository Name: f19-x86_64
 Repository URL: http://mirrors.kernel.org/fedora/releases/19/Fedora/x86_64/os/

3.
 Go to "Content" -> "Sync Management" -> "Sync Status"
 Select/Check Repository (f19-x86_64) and "Synchronize Now"

Actual results:

Error message (after 2 minutes):
"There were errors syncing repository 'f19-x86_64'. See notices page for more details."

Additional details is empty.


Expected results:

Downloaded packages in new repository.

Additional info:

1) Ineternet access from Katello server through proxy works:
# curl -X GET http://mirrors.kernel.org/fedora/releases/19/Fedora/x86_64/os/repodata/repomd.xml --proxy http://myproxy:3128

2) There is no file /etc/pulp/pulp.conf (Katello 1.4) and there is no section with proxy settings in pulp config directory /etc/pulp/:
# grep -i proxy -r /etc/pulp/
