[Gauge] Add threshold support to Gauge

[corteggiano]

React-components Thresholds

thresholds can be represented in two ways:

1. by just coloring the gauge
2. by displaying a thinner outer line surrounding the gauge and coloring the gauge. example:

in this example: there are 3 thresholds:
A = threshold of < 400 and is green
B = threshold of < 500 and is orange
C = threshold of < 700 and is red

since the value of the gauge is 300 then threshold A is met and the gauge is colored green

please ignore adding the normal text since that is not supported by our threshold type definition

Dashboard Thresholds

Add ability to:

• Create/Update/Delete thresholds
• Change threshold colors
• Change threshold styles between
  • show as outer ring
  • show as just color

Acceptance criteria

Beta Give feedback

1. Thresholds can create an outer dial AND change color of gauge
2. Thresholds dont create outer dial but change color of gauge
3. Meeting a threshold changes the inner dial's color
4. Users can add thresholds to
