Mark helloweb-ruby as broken, but let others part of helloweb/helloword
story to live.

Based on patch by @romain.

One of solutions for random 502 errors from caddy is to fully disable
HTTP2 protocol ( https://github.com/mholt/caddy/issues/1080 )

We run Caddy with HTTP2 enabled by default, as we can enable/disable it per
each slave, but in some environments it might be just better to fully avoid
HTTP2 codepaths in Caddy.

The IP used by frontend can be different than the real endpoint, and unknown
for the frontend itself, so make it catch-all to allow access.

Because of misleading tests (Accept-Encoding with gzip was always set by
requests, fixed in "caddy-frontend/test: Workaround requests issue with
Accept-Encoding") the original commit "Fix/caddy frontend prefer gzip type
zope" did not really fixed the issue for type:zope backend.

requests set Accept-Encoding header, but in the testr environment we
want to have full control over its behaviour, thus not setting any header if
not really wanted.

As there is not known way to avoid setting the header (skip_accept_encoding is
internal to httplib) set dummy Accept-Encoding header, which is enough for our
environment.

Hopefully fix the random failure with:

Also publish the fingerprint of the server ssh key, which addresses this warning in the correct way (I feel) and since we can publish the fingerprint, why not.

Since "stack/monitor: Add auto-restart on certificate-authority section"
certificate authority is correctly exposed in supervisor with its hash.

Remove all references to deprecated directories. The promises inside monitor-directory:promises directory are not run anymore by slapgrid. The scripts inside monitor-directory:reports are not run either.

In this PR, we just update the directory location:
 * promise directory is now etc/promise (${directory:promise})
 * reports directory is now bin (${directory:bin})

so that on first connection clients can check the fingerprint key
instead of blindly accepting it.

This seem to be needed "sometimes", apparently on the first connection
after server is started, but this was not investigated much.

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
