[Proposal] Add live visualization of manager terms in UI

[jtigue-bdai]

Proposal

Add configurable functionality to plot the manager based environment terms (i.e. action, observation, rewards, etc) in the UI. This should be able to handle arrays of 1D signals over time and 2D+ or greater signals (i.e. images)

Motivation

To aid in debugging and evaluation of environment execution.
