In datastore client, use main user auth token

[fm3]

Description:

• The datastore routes were attempted without auth, not prompting the user for a token. adding require_auth=true for use cases that can never work without token
• Remove datastore-specific tokens. The datastore can accept the main user auth token anyway.

I’m uncertain about the remaining usages without require_auth. For public datasets/annotations, they don’t need to prompt the user for tokens, but private ones won’t work without them. Not sure what we should do in this case.
