refactor(dynamic_routing): enhance metrics to include separate enteries for all consecutive attempts happening for a payment

[prajjwalkumar17]

We already have the DB schema in-place, the change that needs to be done is as follows(which will help us for the accounts where smart-retries are enabled):

Population of every attempt's data to the dynamic_routing_stats table (right now we are only considering the last attempt's data). This can possibly be done by considering the first and last payment in the chain of attempts being made, or else we can consider every attempts happening, the point is which dynamo connector to choose.

Payment Connectors	Dynamic Routing Connectors	Payment Status
Stripe	(Adyen, BOA, Stripe)	Failure
Adyen	(Adyen, BOA, Stripe)	Failure
BOA	(Adyen, BOA, Stripe)	Success

So which connector to choose from the dynamic routing list of connectors.
