* `name` must be unique on this node
 * for historical reasons, "ff_system" is a reserved string and cannot be used as a `name` or `remoteName`
 * a `database` plugin is required for every namespace
 * if `mode: multiparty` is specified, plugins _must_ include one each of `blockchain`,
  `dataexchange`, and `sharedstorage`
 * if `mode: gateway` is speicified, plugins _must not_ include `dataexchange` or `sharedstorage`
 * at most one of each type of plugin is allowed per namespace, except for tokens (which
  may have many per namespace)
