In "direct zope access" ports, the shared frontend is not used, so
the argument that long timeout consume resources on shared server does
not apply here.

A timeout of one hour was choosen arbitrarily, a value that should be
large enough for normal requests and more than the default 60s timeout
that we hit in the "wait for activities" step when running zelenium
tests.

In 51740961 we "started testing new version of setuptools" and `BUILDOUT-NEXT` test suite was set to use this `software/buildout-testing/software-next.cfg`.

In nexedi/slapos!425 we started to depend on very recent setuptools and updated to 40.4.3 .

This `software/buildout-testing/software-next.cfg` kept using this old setuptools and `BUILDOUT-NEXT` test suite failed to build in a loop.

The test suite was already changed to use `software/buildout-testing/software.cfg` (ie. it's same as `BUILDOUT` but testing slapos.buildout's  `next` branch instead of `master` ), so I think this profile is not needed currently.

  Before call uninstall, the pin is verified and it can cause error if picked version is mandatory.

Just asserting Location header is not enough, as http status code value is
important for the implementation, so assert for its value.

Also fix https-only redirect status code value, which supposed to be FOUND,
not default MOVED_PERMANENTLY.

   The version 1.0.84 was used by an existing tag on the
   version control, so it would be inconsistent to use this
   version number.
