Implement load feedback mechanism

Allow providing feedback to the message puller on the load of the service. Example:
Suppose we have 3 types of messages (A, B, C) with the following resources required to process the messages:
- message A requires 4Gb RAM
- message B requires 1Gb RAM
- message C requires 10Mb RAM
Currently the puller will try to handle up to concurrency
messages simultaneously, but if we have a 32Gb RAM machine and already handling 8 messages of type A
- we just don't have capacity for any other message.
Instead of replying to all the events with OutOfCapacityError
- it'd be better if the puller will hold the messages until the capacity is available.
