Pass multiple users to webacl.resource.addRights

[srosset81]

Currently, to give several users rights to the same resource, we have to call the webacl.resource.addRights action once per user.

This is costly in terms of performance, as the addRights action performs a lot of checks (locally, it takes almost 1 second per user).

My suggestion would be to allow multiple users to be passed in this way:

await ctx.call('webacl.resource.addRights', {
  resourceUri,
  additionalRights: {
    user: {
      uri: [user1, user2],
      read: true
    }
  },
  webId: 'system'
});

If I'm not mistaken, all we need to do is change these lines:

I suppose this has changed to those lines:

Will create a PR :)
