Currently the timeout for a wsgi server successfully binding to a port
and for a probetest background service to finish starting are hard coded
to 30 seconds. While a reasonable default for most configurations, a
small virtualized environment may need a little more time in order for
probe tests to complete successfully.
This patch adds a 'bind_timeout' option to the DEFAULT section of the
main wsgi servers' config. Also a new [probe_test] section and
'check_server_timeout' option to test.conf
