fix(slider) - Label showing all the time instead of using marker

[Alex-NRCan]

Description

• Default stepping value for time-slider to 1 day;
• New style on the active thumb to visually indicate that it's selected and can be moved by keyboard;
• Small style change on the label (make it a bit smaller);
• Renaming 'onValueDisplay' to 'onValueLabelFormat' to better align with 'onValueLabelFormat' that comes from Material UI and to better distinguish from 'valueLabelDisplay' (from Material UI) which has different meaning
• Added support for disableSwap and labelSpread attributes
• Cleaned up attributes spreading on the Component
