feat(frontend)(api): add sharepoint datasoure (#61)

Added implementation to allow ingesting of documents from sharepoint
datasources. The implementation requires one to set up a client app in
their ms environment with certificate crendentials that allow access to
the desired sharepoint resources.
This implementation recursively sources documents from sharepoint the
list of sharepoint folders provided during the set up.
