Feat/directory component

[davidlee04]

Notes:

• I added the directory form component to be a part of the provider custom content in the subsections. But the state is being completely shared across all sections which means the state needs to be lifted whenever the Directory component is called. I didnt add this since I don't know how it will be decided which component form to show for each subsection.
• I added the directory view component to the provider page.
