ref(dependency-graph): Adding more context to the dependency graph

[IanWoodard]

This change adds context about whether a given node in the dependency graph is a docker compose service (leaf) or a devservices service. This enables us to avoid cycles when we have docker compose services with the same name as the devservices service which is a common thing we see such as with snuba and it's container.

This is required to enable the improvements we are looking to make to the status command: https://linear.app/getsentry/issue/DI-647/rework-status-command.
