Feature/sdk reporting

[EspressoTrip-v2]

Connection SDK reporting.
Stores sdk data for user connections on the instance. Open edition storage is disabled by default, so no impact on attached databases. Event emitter engine is extendable for other use cases as it is attached to the service context.

Additions:

1. Event emitter engine
2. Posgres report storage factory
3. Mongo report storage factory

Basic flow:

• User connects, user information, jwt and meta are stored
• User connection refreshes or reconnects, if the connection event is within the same day the stored initial connection is updated. Else new connection is stored
• User disconnects connection is updated as disconnected, using the previously connected time for long running connections
