Add APIKey performance optimizations #37
Description
We should add the user info for an APIkey to in-memory dictionary ... the use of APIkeys significantly and dramatically lowers performance ... we maybe need to reconsider a JWT-based approach for M2M tokens using an accountId and Secret ... either for user-specific signing or maybe we could create an endpoint where a JWT could be created with userId & secret.
The fact that we seem to be adding 50-250ms on the initial request and 10-40ms for additional requests with API keys is too much ...
