Add friendly_name to EntityCreate and EntityUpdate

[mutzl]

not sure, if you consider this a bug or more a feature request, but...

I'd like to set a friendly_name when creating or updating an entity.

The method is missing a parameter name or friendlyName similar to unit or icon.

EntityCreate(object? @entityId = null, object? @state = null, object? @icon = null, object? @unit = null, object? @options = null, object? @attributes = null)

When trying to set this via the attributes object, it get's simply ignored and always the second part of the entityId is used instead. (sensor.my_sample -> my_sample).

we also need it during creation. BUT.. if you first create entity and then go in update with the callservice, you can add icons friendly_name and so on
