RPM Support

I tried with both file and rpm repos, if i specify a proxy url, username and password, i can check pulps' db and see:

pulpcore=# select url, proxy_url, proxy_username, proxy_password from core_remote;
                              url                              |          proxy_url          | proxy_username | proxy_password 
---------------------------------------------------------------+-----------------------------+----------------+----------------
 https://jlsherrill.fedorapeople.org/fake-repos/needed-errata/ | http://192.168.122.182:8888 | admin          | redhat

so i am fairly confident that the username and password are being set properly. However, when i sync, i get:

407, message='Proxy Authentication Required', url=URL('http://192.168.122.182:8888')

looking at my squid logs, i see:

1625605398.930 0 192.168.122.143 TCP_DENIED/407 4235 CONNECT jlsherrill.fedorapeople.org:443 - HIER_NONE/- text/html

So I believe pulp isn't properly sending the proxy auth correctly?

Note that my curl command:

 curl  -vv   -X GET  https://jlsherrill.fedorapeople.org/fake-repos/needed-errata/repodata/repomd.xml   --proxy http://192.168.122.182:8888  -H 'Proxy-Authorization: Basic YWRtaW46cmVkaGF0'

works without issue
