Colorize severity in table output (#1284)

Browse source 
* Colorize severity in table output

- Create flag "--no-color" to allow disabling the color. By default its enabled.
- When "--no-color" not specified highlight severity in its color:
  - Critical -> Bold Red
  - High -> Red
  - Medium -> Yellow
  - Low -> Green
  - Negligible -> Blue
  - Note: Golang doesn't have all colors available. Also, doesn't seem to be able use hex codes properly.
- Add termenv to check if the terminal color profile supports colored output. If it doesn't default to noColor
