Limit the number of requests sent per connection in DoH tests

This commit ensures that only a limited number of requests is going to
be sent over a single HTTP/2 connection. Before that change was
introduced, it was possible to complete all of the planned sends via
only one transport connection, which undermines the purpose of the
tests using the quota facility.
