Allow superdatepicker to be disabled

[stacey-gammon]

Would love to make it disabled for the case of per panel time ranges, when the "inherited" toggle is on.

@stacey-gammon Will this still block you even with the design that doesn't include the toggle?

[stacey-gammon]

Oh gosh, I'm sorry, I totally glossed over that change! You are right, shouldn't need this in that case. Want me to close or just unlabel urgent?

[cchaos]

I'll unlabel it, but it might still be a nice to have.

@cchaos we probably want a quick design pass on how the date picker should look / communicate that it is disabled

[cchaos]

It should just make the whole input look like out disabled inputs.

Hopefully it's all hooked up to the right layout components that it should get those styles.

[chandlerprall]

Should the disabled state prevent the datetime popover from opening, or should it open but all its controls be disabled?

[cchaos]

If disabled=true is added to the EuiSuperDatePicker at the top level, it should disable everything from opening.
