UI Shell header allow dropdowns from icons

[gptt916]

Use this template if you want to request a new feature, or a change to an existing feature.

If you are reporting a bug or problem, please use the bug template instead.

Summary

Currently, the UI shell is quite restrictive in that users are only allowed to use the dropdown menu with text, and the icons on the right hand side do not support dropdown menus.

Justification

More flexibility in configuration of the UI shell.

Desired UX and success metrics

Either:

Allow the icons on the right hand side HeaderGlobalAction to have a drop down.

Or

Allow the dropdown menus in the nav section on the left to display an icon instead of strictly text.

"Must have" functionality

Icon + dropdown functionality.
