This fixes up the support for the json schema definition for {"type": "number",  "enum": [ 1.0,  2.0] }

   It relies on data-format to overcome the limitation of select fields that only output strings on input.value.

   If the field is number the field is handled as float, and not as integer anymore.

   We should use schema_url rather them json_url on validationJSON, since the json_url is the software.cfg.json while schema_url is the actual url for the schema.

  Like in WebSite_login, came_from is an URI Template so we must expand the URI to handle the {&n.me}
  that can be present on the URL.

   Use proper trademarks for the login buttons

See merge request nexedi/slapos.core!379

    This prevent not configured sites show the sign-in buttons w/o proper configuration, in other words, broken buttons.

  Just let configuratior handle everything

   Since the ID is used, it is important to "enableGlobal" before set conversion server configuration.

   Roles had duplicated names and were generating unecessary diff

This commit remove the following 2 commands:
 * slapos cache lookup
 * slapos cache source
And introduces the following 3 commands:
 * slapos cachelookup binary-sr
 * slapos cachelookup url
 * slapos cachelookup pypi

This is useful to check if some objects are in shacache for buildout.
Please note that the commands are using the latest keys (introduced in
slapos.buildout!26)

   On xml serialisation we support a more restrict scope them the whole json schemas and on json-in-xml, despite the fact we could support all, not everything is suitable for form generation.

   The both "meta schemas" are a variation of the draft exclusively for UI rendering purpose.

   Keep this code would only make things confusing, since this code is mostly an archive

   If they exist.
