Event Lineage: Map Subscriptions to Graph Edges

[Cali0707]

Problem
To construct the event lineage graph properly, a function should be created that maps the subscription struct into a Edge struct. Specifically, this Edge struct should:

1. Have the self property reference the subscription itself
2. Have the from property reference the channel itself
3. Have the to property reference the subscriber
4. Have the transform function be NoTransform

Additionally, if the subscription has a reply field set, there should be another Edge struct. This Edge struct should:

1. Have the self property reference the subscription
2. Have the from property reference the subscriber
3. Have the to property reference the reply destination
4. Have the transform function be NoTransform

If the subscription has the deadLetterSink property set on the delivery field, then another Edge should be constructed. This Edge struct should:

1. Have the self property reference the subscription
2. Have the from property reference the channel
3. Have the to property reference the DLS
4. Have the transform function be NoTransform

This function should accept the subscription struct, as well as a map[duckv1.Destination]Vertex.
