Consider how to treat discrepancies in success and version fields of signer responses

[isabellewei]

Currently, signer responses received by the combiner are filtered for successes in CombineAction. Consider whether we want to handle discrepancies in the success and version fields of responses differently

The combiner response separation also makes it difficult to: process/use returned domainState or quotaStatus in the case that a PNP or domain /sign call failed with an out-of-quota and signer responses. Ideally, we would want to process & return quota returned from those responses to give users more information about these failures.

Refactoring this is likely a more involved change and will require additional testing.

Sprint planning:

• ticket to investigate how to deal with discrepancies
• but might need to restructure files
• Alec - slightly unintuitive behaviour in the code (hard to reason about logic)
• Eela - won't block functionality (more nice to have)
• Alec - probably doesn't need to happen pre merge

This is also related to why we can't return quota status information from the combiner on pnpSign responses
