ESC 6B Edge Composition

[brandonshearin]

Description

This changeset adds the edge composition handler for the ESC 6B edge.

• new GetADCSESC6bEdgeComposition function in esc6.go, follows the same approach as the handler for ESC 6A
• four helper functions in esc6.go that each handle a different part of the traversal needed for composition
• the repeated boilerplate composition component was added to the shared ui

Motivation and Context

when a graph is rendered on the explore page that contains an esc 6b edge, the user should be able to click on the edge, and then click on the "composition" panel of the entity info content panel, and a new graph should render of all the implicit paths that a 6B edge needs.

How Has This Been Tested?

Looks good! Could you please update the 6b integration test to test for the edge composition in one of the harnesses?
