Allow users to set depth of lineage graph in UI

[wslulciuc]

In the Marquez UI, the user is not provided with the option to set the depth of the lineage graph even though the LineageAPI defines a depth param. Therefore, the lineage call defaults to 20 on the backend.

Benefits:

1. Reduce lineage graph render complexity i.e. a dynamic depth of N would return a more digestible lineage UI view for debugging
2. Reduce lineage graph call response time i.e. a dynamic depth of N would avoid returning a lineage graph with all connected nodes from origin node
