Use gitlab_ui.scss instead of all the bootstrap imports
Allow the ../node_modules path from gitlab_ui.scss to resolve

- Apply new styles for header, padding, border, and fonts
- Remove bootstrap 3 backward compat code

- Use rems instead of px to set default font-size
    This allows users to change font sizes in their browser and it will
    affect the view in our application

- Also remove boostrap 4 migration adapter

Replaces .card-header > hX.card-title with hX.card-header to remove
.card-title. At a occurrence where bold styling is not necessary,
div.card-header is used instead.
By full removal of .card-title at the moment, all workarounds for
BS4's card-title are removed as well.
