Instead of having an hardcoded timeout that users will hit anyway even
if they increase publisher timeout, set this timeout value to be
slightly higher than publisher timeout. This way publisher-timeout can
be used to allow longer requests and it's generally more consistent.

We already had haproxy configured to stop serving requests longer than
this duration, but the requests was still being processed by zope.

By adding such default in publisher-timeout, zope will stop processing
the request after the timeout.

This is slightly different behavior, because before this change the
request was still being processed, even if the client did not get the
response it may make change to databases.
Users who want to keep the previous behavior can request with
publisher-timeout parameter null.

When objects are not supposed to accept extra properties, setting
additionalProperties to false allows schema validator to detect typos
in key names, or usage obsolete keys.

Since https://github.com/mroonga/mroonga/commit/35f593037c2d8f5a497349ff98f3a3ce31ee95de
install.sql has been split in install.sql and update.sql, adjust the
script to source both.

install.sql only contains INSTALL PLUGIN, it's safe to run it on every
update (that's what we always did).

This fixes a regression that mroonga user functions were no longer
available after d0589a41 (version up: MariaDB 10.3.35/10.4.25, groonga
12.0.4, mroonga 12.04, groonga-normalizer-mysql 1.1.8, 2022-06-10)

Thanks to migration to json-in-xml serialisation some lower level bugs has
been discovered with value types in the profiles, so simply fix it.

default and kvm-cluster software types are now json-in-xml, so they accept
and return json-in-xml.

Update tests to show that xml and json-in-xml serialization works.

Note: There was invective to publish with pure XML serialisation, but it is
wrong idea because:

 1) serialisation in the software.cfg.json is provided for both ways
 2) requesting instances with given serialisation by profiles expect same
    serialisation

Request resilient instances with serialised, as they reply with json-in-xml.

Fixes this warning when running test:

    UserWarning: Error validating request parameters against schema definition:
    RefResolutionError unknown url type: 'instance-input-schema.json'

jsonschema (the python library) support this kind of refs when using
version draft-06 but not when using draft-04.

json-language-features (from theia text editor) does not understands
file.json#/ references, it complains:

    $ref '/' in 'file://...' can not be resolved.(768)

but not using the trailing / works fine

b'💥' is a SyntaxError in python.

Instead, switch to accessing options from option variable and apply
this to other options from this part.

This fixes this issue:

      Installing switch-softwaretype.
      Installing favicon.ico.

`depends = {slapos-cookbook:recipe}` bug when `virtual-env-base` is used in an instance.cfg.

Now, `virtual-env.cfg` will create an instance by default.

This instance will publish `activate` script path.

This fixes 92130619 formatting.

erp5.recipe.w3validator is not installed, it was just a version pin
because when running buildout updating the software needs a version
pin, by now all softwares must have been updated.

These tests are still using `python setup.py test` which installs
missing packages to their latest versions. Recently, certifi (a
requests dependency) published a new release with python3 only
syntax, so running the test now got an error installing missing
packages:

    File "parts/slapos-package/playbook/roles/standalone-shared/.eggs/certifi-2022.5.18.1-py2.7.egg/certifi/core.py", line 17
        def where() -> str:
                    ^
    SyntaxError: invalid syntax

The `playbook/roles/standalone-shared` is defined on the test suite
as instance parameters, so it seems we can not already install this
package directly from playbook/roles/standalone-shared because
test suite may define something different. For now, just install
requests. All this will have to be addressed when we change this
test to pre-install packages with slapos and use `python -m unittest`
instead of `python setup.py test`.

These two options were unusable for software releases using python3.

This also adds test coverage for the recipe.
