Add audit events for PaymentStart update

[lsampras]

Created from #4525

This covers adding events for PaymentStart operation

This event should include the payment data similar to PaymentCancel

It should also include any metadata for the event
e.g reason for payment rejection, error codes, rejection source etc

Hey @lsampras , I would like to work on this issue, can you please assign this to me?

[kaustubh1106]

Hey @lsampras , I need some clarity as I gone through the reference #4166 ,I have to make changes in Pyament_update.rs in updateTracker trait ?? am I right? and also I want to ask do I need to add enum in Audit_event or I have to use any existing enum???

[lsampras]

@kaustubh1106 yeah you are right about the trait there, and you can add another variant in the same enum...

@lsampras sir can please tell me if there is something wrong with the PR?

[lsampras]

@kaustubh1106 no worries everything seems correct, I had approved the PR as well,
there's some CI failures, would you be able to take a look at that?

@lsampras Check compilation on MSRV toolchain (ubuntu-latest)
Sir I am unable to fix this and

and following error req_state i think you suggested me

[lsampras]

@kaustubh1106 you should be able to fix it by adding the suggested import
(use crate: events: :audit_events: :AuditEventType;),
can test it locally via make clippy
