Bug 1297683

Description of problem:
time hammer content-host list --organization <orgname>
Error: Request Timeout
real    2m2.340s
user    0m1.179s
sys     0m0.220s

Version-Release number of selected component (if applicable):
satellite 6.1.4

How reproducible:
unknown
(in this environment here with >500 content hosts the issue always exists)

Steps to Reproduce:
1. register more than 500 content hosts
2. hammer content-host list --organization <orgname>
3.

Actual results:
Error: Request Timeout

Expected results:
<result should be displayed>

Additional info:
- using ":request_timeout: -1", the result appears
- enforcing paging, the result also is displayed.  I.e. "hammer content-host list --organization <orgname> --per-page 300".  Using "--per-page 500", the timeout is hit again.
- The time for execution suggests that the code contains a bug.  From what I understand, this should be a simple database query.  Instead it takes a very long time:
