Sticky Footer

In most pages including forms, we want the footer to be sticky on the bottom of the form when the form is small enough, or on the bottom of the page when the form requires some scrolling.

`nsi-sticky-footer` is a simple wrapper component which will style the footer as expected (with a top border and the buttons aligned on the right). It is working with two `ng-content` blocks:

- the main `ng-content` allows to display buttons on the right of the footer
- an optional `footerNote` allows to display some text on the left of the footer

You can display a note on the left side cancel save
