refs #1 - update abort method on MQHandler requests

[pccosta-pdm]

As descripted in issue:

We have a situation where we have a wallet containing multiple DIDs that the browser is listening on. However, the browser restricts the number of simultaneous requests that can be made. To address this, we've created a manager to rotate through the DIDs.

Every so often, the "root" DID sends a message to the DID that needs to be closed, asking it to read the message and finish the request (which is stuck in a loop, because MQ is waiting for new messages).

However, this approach isn't scalable because, while the browser limits parallel requests to 6 (as an example), the delay in rotating the DIDs and the unnecessary requests for sending messages to cancellations increases as the number of DIDs to be rotated grows.

There have been some updates to OpenDSU that enable calling methods like "stopWaitingForMessages" However, these checks happen after or before processing, without interrupting or aborting the current request (the DID/MQHandler still keeps the active request even after the "stopWaitingForMessages" method has been called)`.

The pull request suggests the update below while maintaining compatibility with existing functions in public methods and addressing issues related to aborting the request.

W3CDID:

• The "readMessage" method in W3CDID now returns the function to abort the request, without exposing the abortController.
• Verification of DID being enabled for reading messages is now checked before calling MQ methods.

MQHandler:

• Message reading methods now optionally accept an abortController parameter, which is passed throughout the request chain. This allows for aborting the operation at any stage of message processing.
• Fixed empty returns. Even after aborting the request, the callback was still pending, awaiting a response.
• Added a check for the stopReceivingMessages parameter before calling a new method or processing. For safety, request abortion is also verified.

PollRequestManager:

• Internally, the "Request" method has been refactored to simplify the code
• Unified the methods (destroy and cancelExecution) to abort the request. Now, when an abort occurs, it is caught and rejected by createPollingTask, providing a response to the callback instead of being stuck in a callback with no response.
• createPollingTask method has been changed to return a promise instead of using the setExecutor method of the Request function and afterwards using the "executers register"(promiseHandlers) to deal with the response. This allows the removal of resolve and reject methods of the Request function
• execute method in the "Request" has been updated to include an abortController in request options.
