Support for Room Creation with initial Room Metadata

[calvin-seo]

Is your feature request related to a problem? Please describe.
kotiln-sdk's RoomServiceClient only supports creation of room without metadata

server-sdk-kotlin/src/main/kotlin/io/livekit/server/RoomServiceClient.kt

Lines 19 to 46 in be855bb

	/**
	* Creates a new room. Explicit room creation is not required, since rooms will
	* be automatically created when the first participant joins. This method can be
	* used to customize room settings.
	*/
	@JvmOverloads
	fun createRoom(
	name: String,
	emptyTimeout: Int? = null,
	maxParticipants: Int? = null,
	nodeId: String? = null,
	): Call<LivekitModels.Room> {
	val request = with(LivekitRoom.CreateRoomRequest.newBuilder()) {
	this.name = name
	if (emptyTimeout != null) {
	this.emptyTimeout = emptyTimeout
	}
	if (maxParticipants != null) {
	this.maxParticipants = maxParticipants
	}
	if (nodeId != null) {
	this.nodeId = nodeId
	}
	build()
	}
	val credentials = authHeader(RoomCreate(true))
	return service.createRoom(request, credentials)
	}

so if you want create a room with initial metadata, you have to request room update once you created room first

Describe the solution you'd like
simply add additional parameter for metadata, then pass it to the roomRequestBuilder

Describe alternatives you've considered
maybe change the method to allow passing CreateRoomRequest just like go-sdk
