All the controls should be accessible by keyboard and Calendar shortcut keys should work properly

[SanjayBhargavS]

Accessibility of the datetimepicker can be improved by providing keyboard navigation.

Here are few examples of Keyboard navigation:

• When a user hits the tab key, the focus should move inside the dialog instead of closing it.
• Focus should move to all the controls (next button, previous button, year/decade/century toggle button, time picker) using the tab key .
• To select the dates/months/year/decades/century via keyboard.
• Navigate with the help of keyboard in the time picker section.

This is very important factor, since due to accessibility requirements, cannot use this widget now due to that.
