Add html tool tip for displaying node information

[davidsharp7]

Description

Currently the Marquez UI compresses dataset/job name under each node if they are over x characters which leads to a sub optimal user experience when browsing nodes on a graph. The current tool tip just displays if the object is a job/dataset and so is not massively helpful.

Proposed Solution

Add an HTML tool tip which on hover over displays details about the node. Initially I would like to just update

https://github.com/MarquezProject/marquez/blob/main/web/src/components/lineage/components/node/Node.tsx

and reformat the node label to display

node type (dataset/job)
Namespace
Object Name.

This feature could be expanded to include multiple facets but that is a discussion for the wider community.
