* Add params to set_id block arguments
Pull request #331 added a block to the ObjectSerializer.set_id class
method, which allows passing a block to the set_id method. Currently
this block takes only one argument `record`:
```
set_id do |record|
"#{record.name.downcase}-#{record.id}"
end
```
This PR adds another argument `params` to the block:
```
set id do |record, params|
params[:admin] ? record.id : "#{record.name.downcase}-#{record.id}"
end
```
This customization can be useful in situation where we serve different
clients that may need different IDs. One nice side effect is also that
the `set_id` method has the same method signature as the `attribute`
method.
