Added API extensions to detect sorting/pagination features

Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/neutron" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    Added API extensions to detect sorting/pagination features

    Those features are available only when allow_sorting and
    allow_pagination options are enabled (the current default is False).

    They don't depend on plugin support, because when plugins don't
    implement them natively, emulated mode is applied by API router itself.
    So to make it plugin agnostic, we introduce a way to register custom
    per-extension checks to override support detection for cases like that
    one.

    Now that we have a way to detect support for those features via API,
    there is little reason to keep tempest configuration options to enable
    those features. Instead, just inspect [network-feature-enabled]
    api_extensions option in tempest.conf.

    Now that DEFAULT_ALLOW_SORTING/DEFAULT_ALLOW_PAGINATION constants are
    used in a single place only (in allow_sorting/allow_pagination
    definitions), removed them and replaced with a literal.

    Added first in-tree API tests for /extensions entry point.

    DocImpact Update API documentation to cover new extensions.
    APIImpact Document the new extensions.

[Ihar Hrachyshka (ihar-hrachyshka)]

We maintain neutron API reference in neutron-lib, so marking openstack-api-site part of the bug as Invalid. Ideally it would be a duplicate of neutron part, but I don't see such a feature in LP.

    Move valuable API info from neutron-specs repo

    This information is stored (unlinked) in neutron-specs repo under
    misc/api/networking_general_api_information.rst This patch just moves
    the contents into api-ref, where they seem to belong.

    Note that the contents are not current in some parts. For example, it is
    said there XML format of requests is still supported, which is not true
    for quite a while. This contents will be cleaned up in follow up
    patches. For now, I keep the text intact to ease reviewer's life.

    Adding two documentation bugs to be closed by the patch because the
    information missing in api-ref is already included in the bits copied by
    this patch.
