   ## Overview
   
   <!-- Please give a short brief for the pull request,
        what problem it solves or how it makes things better. -->
   
   This test can time out with the following stack trace because [ibrowse sends 
{error, retry_later} under certain conditions](url) [1] which causes 
test_request:request/6 to sleep and retry [2], which can result in this failure:
   ```
       chttpd_dbs_info_test:79: -dbs_info_test_/0-fun-20- 
(should_return_500_time_out_when_time_is_not_enough_for_get_dbs_info)...*timed 
out*

        Also remember, that CouchDB uses the Review-Then-Commit (RTC) model
        of code collaboration. Positive feedback is represented +1 from 
committers
        and negative is a -1. The -1 also means veto, and needs to be addressed
        to proceed. Once there are no objections, the PR can be merged by a
        CouchDB committer.
