support remote host (suffix, target) for SI and SSI

[remipichon]

• hosts.json

  • name
  • certificates

• suffix must refer to an existing host name

• no suffix is local (via docker socket binding)

• 'local' suffix is local (via docker socket binding)

• when a suffix is defined, we bind it to a host

  • all docker-compose/docker cmd will be prefixed with the certs as ENV
  • never output this prefix, even in dry mode

• check if same ressource name are on different target

• at the moment, instances with name resourceName but different prefix will be discarded
