Currently, the protocol gateway template opens one AMPQ connection to Hono for each tenant that has devices connected to it. When the last device connection for a tenant is closed it would be good to close the corresponding AMQP connection as well.

As part of working on the connection handling here, it would be good to also consider using a timeout for the handleEndpointConnection() request triggering the initial connection establishment to the AMQP adapter for a tenant. The result of factory.connect could be decoupled from the connectGatewayToAmqpAdapter return value here, using an isConnected(timeout) check for the return value instead.

The MQTT endpoints are tracked for each tenant. When the last endpoint of a tenant is
closed, the AMQP connection for this tenant is closed as well.

[eclipse-hono#5] Refactored MultiTenantConnectionManager.
ab79d77 
MultiTenantConnectionManager.addEndpoint() and MultiTenantConnectionManager.closeEndpoint()
now return a future instead of throwing exceptions.

Closing TenantConnections no longer throws an exception if the instance is already closed.
