Add option for Super date field to open picker in one click

[jovancacvetkovic]

Is your feature request related to a problem? Please describe.
The current version of the OUI Super Date Picker opens the picker on second click.
The default state of the field is like this

The first click updates the field to this

and finally the second click opens the picker

Describe the solution you'd like
It would be a great improvement to update the field content and open the picker in just one click.
And in addition to better UX perhaps event focus the start field so that user can use the keyboard right away.

Desired flow would be like this:

• the field is rendered in the default state
  

• the user clicks once into the field and the field is update and the picker is opened

@KrooshalUX can you weigh in on this?

Apologies for delay @seanneumann @jovancacvetkovic - @kgcreative and I synced up on this around the time the issue was filed, I responded that we needed to do a bit of a deep dive on the possible down-stream implications of making this single click ,and the best way to handle single click here. (Not sure what happened on my end but it looks like I didn't actually post the response, how embarrassing)

Currently on my radar is investigating - from a UX perspective - how the two preview states work and express the time previews based on the selection of time range. We are seeing a mis-match in communications (1 day vs 24 hours) so I got caught up in a bit of a rabbit hole on this.

I am going to sync with @AbhishekReddy1127 who has some ideas in his PR on a resolution and then come back to this issue.
