Subscriptions per session

[stdevi]

The current DgsWebSocketHandler implementation allows having one subscription per session:

dgs-framework/graphql-dgs-subscriptions-websockets/src/main/kotlin/com/netflix/graphql/dgs/subscriptions/websockets/DgsWebSocketHandler.kt

Line 37 in 6fea279

internal val subscriptions = ConcurrentHashMap<String, MutableMap<String, Subscription>>()

dgs-framework/graphql-dgs-subscriptions-websockets/src/main/kotlin/com/netflix/graphql/dgs/subscriptions/websockets/DgsWebSocketHandler.kt

Lines 97 to 102 in 6fea279

	override fun onSubscribe(s: Subscription) {
	logger.info("Subscription started for {}", id)
	subscriptions[session.id] = mutableMapOf(Pair(id, s))
	s.request(1)
	}

Shouldn't it be allowed to have multiple subscriptions per session, so the subscriptions[session.id] map wouldn't be overridden on subscribing, but rather the new subscription will be added to the inner map?
