Allow the software release to be correctly instanciated even if not
instance parameter has been configured.

Increase timeout to 15h as with new DeploymentTests we do compile from scratch and it might take a bit more than the previous default of 10 hours which reports false tests failure results.

Adjust the profile after we use switch-softwaretype instead of
softwaretype in slaprunner.

collective.recipe.shelloutput does not work well with Python 3: it
outputs values as bytes, which are printed in the format "!py!b'XXX'".

The new "init" option is used as a replacement.

I don't think we need it here, I probably added by mistake.

Interestingly when running this command it fails the first time with an
explicit error:

    Could not find a version that satisfies the requirement typeshed==0.0.1 (from -r /srv/slapgrid/slappart14/srv/testnode/cqc/inst/test0-0/tmp/soft/a6a44539f462e5e342cf8c714b7c8e5b/parts/python-language-server-requirements.txt (line 22)) (from versions: )
    No matching distribution found for typeshed==0.0.1 (from -r /srv/slapgrid/slappart14/srv/testnode/cqc/inst/test0-0/tmp/soft/a6a44539f462e5e342cf8c714b7c8e5b/parts/python-language-server-requirements.txt (line 22))

But when the command run again, another confusing error is displayed:

    Error: [Errno 13] Permission denied: '/srv/slapgrid/slappart14/srv/testnode/cqc/inst/test0-0/tmp/soft/a6a44539f462e5e342cf8c714b7c8e5b/parts/python-language-server/bin/activate.fish'

md5 has not changed - it is the same package.

We need to access six when calling the 'replicated.replicate' macro.

"max" and "int" became directly accessible in slapos.recipe.template.

The kvm software release was recently modified to use
slapos.cookbook:switch-softwaretype instead of the deprecated
slapos.cookbook:softwaretype.

The latter uses ConfigParser to generate
buildout-switch_softwaretype.cfg from template-*.cfg. However,
ConfigParser changes the section keys to lowercase, as shown in the
following example:

>>> from six.moves.configparser import ConfigParser
>>> from io import StringIO
>>> c = ConfigParser()
>>> c.readfp(StringIO("[FOO]\nBAR = BAZ"))
>>> s = StringIO()
>>> c.write(s)
>>> s.getvalue()
'[FOO]\nbar = BAZ\n\n'

This behavior is not present with
slapos.cookbook:switch-softwaretype.

This change is related to 11210de0.

Dead code from the previous commit has also been removed.

[fish](https://github.com/fish-shell/fish-shell/) has a nice user experience in its default configuration.

[tmux](https://github.com/tmux/tmux) I don't use myself, but there's a component, so let's enable it as well.

Promise plugins are important part of the instantiated configuration, thus
have to be checked for changes.

This promise will check that certificate matches the key and will check
that it is renewed before 15 days before expiration.

For some cases on-renew is not needed, so allow empty one in case if it's
not provided.

and other probably useful information.
