=== ISSUE ===
With Milk, we introduced a change related to the active state color
meaning that the `active` state should use the following SCSS variables:
- $o-component-active-bg for the background ;
- $o-component-active-color for the text ;
- $o-component-active-border for the border.
The datetime_picker component was currently using the primary variable
which is not the expected color. This change also affects the different
states of the datetime picker (hover, click, ...)
=== AFTER ===
We apply the right variables on the component for consistency purpose,
and make some little design adjustments using `:before` and `:after`
pseudo elements to stylize the different states.
