cliff complete command only supports bash, but fish offers much more user friendly
completions.

cliff uses a pluggable system, but this where new shell completions can be registered,
but the plugin (CompleteFish) can not access the command manager to get more
details about options, since fish can also show help of suggestion, we want to
access the help of each option to show this during suggestions.
Also we want to make some more clever suggestions (for example slapos node start complete
with services identifiers).
For these reasons we need to register a command to replace the default complete command
and can not achieve this with simply a cliff.formatter.completion entry point.

This can be installed with:

    slapos complete > ~/.bash_completion.d/slapos
    slapos complete --shell fish > ~/.config/fish/completions/slapos.fish

    The user should request to Mantainence to "Open" a contract.

    - Invoice is generated 15 days before next period and a RR is created
   - 15 later a stop warning is sent (or when invoice expires)
   - 7 days later all instances are stopped if RR still open
    - 5 days after the user is informed his instances will be removed if payment is not done
    - 10 days after ALL his instances will be removed (for safety, as instances can be scaled faster if needed)

So, we assume:

   User is informed 22 days in advance before his instances stop to work, and if nothing is done 15 after (or 37 days after the first request to pay), we just remove all.

    This email is already part of Subscription System. Regularisation Request is only for later payments.

By following feature of JSON Schema Draft-06 render a structure like:

  "element": {
    "oneOf": [
      {
        "const": "value1",
        "title": "Description1"
      },
      {
        "const": "value2",
        "title": "Description2"
      }
    ]
  }

To:

  <select size="1">
    <option value=""></option>
    <option value="value1">Description1</option>
    <option value="value2">Description2</option>
  </select>

JSON Schema types array and object are stringified to be safely represented
as option keys.

slapos_accounting: In case of Subscription, generate invoice 15 days earlier them begin of the next period.

After 1.6.1 was deployed we have two processes, stop the redundant process.

In 58fbaabf (svcbackend/standalone: use shorter names for supervisor sockets
, 2020-07-17) we changed the socket path from supervisord.sock to a shorter
sv.sock, but this caused issues when updating running slapos node instances,
because this was trying to start a new supervisord process using the new
socket path, while the old one was still running.

To keep services running after upgrade, introduce a compatibility layer in
this socket path - if we still have a supervisord running with a socket at
this previous path, keep using this old socket name.

Output is already captured on SlapPopen instances and the output
is available with output attribute.
