Issue:
Bug: Include the pre-routing connectors in apple pay retries



Currently for apple pay pre-routing is done before the session call and only one connector is decided based on the routing logic. Now since we want to enable auto retries for apple pay we need to consider all the connectors form the routing rule and construct a list of it. After which this connectors should be filtered out with the connectors that supports apple pay simplified flow.

Once this is done there will be a list of connectors with which apple pay retries can we performed.

In the above response we can see that apple payment got failed with stripe and it was auto retried with adyen based on the configured routing rule.

-> The routing rule configured during test is as shown below
