[Feat.Req] Handle TAP payment faults

[aasseman]

Problem statement
Currently TAP Agent ignores payment faults.

Expectation proposal
Faults can be invalid receipts (wrong value, receipt replay, etc), invalid RAVs, or aggregation denial.

For each type of fault, criteria should be determined for deciding when to stop doing business with a problematic sender.

The signal to reject a sender should be communicated promptly to the service instances for it to be effective.

EDIT:
Sender denial move to issue #103
