[katello-devel] Added ability to configure pulp's HTTP Proxy settings

[Cliff Perry]

Also made it generic enough that if other future items also wanted to
suck up these settings they could.

Updated the wiki to note this new addition to options for
katello-configure.

https://fedorahosted.org/katello/wiki/Install

Example usage:
 1) katello-configure --proxy-url=http://barbar.example.org
--proxy-port=2040
 grep -i proxy /etc/pulp/pulp.conf
 # Uncomment the below section with appropriate values for proxy
configuration
 proxy_url: http://barbar.example.org
 proxy_port: 2040
 # proxy_user:
 # proxy_pass:

 2) katello-configure --proxy-url=http://foo.example.org
--proxy-port=4242 --proxy-user=stackable --proxy-pass=one2three

 more /etc/katello/katello-configure.conf
 proxy_url = http://foo.example.org
 proxy_port = 4242
 proxy_user = stackable
 proxy_pass = one2three

 # Uncomment the below section with appropriate values for proxy
configuration
 proxy_url: http://foo.example.org
