feat: add oauth support to gsuite

[jychp]

Allow gsuite to use oauth credentials.

Legacy method is used by default for backward compatibility.

@achantavy linter issues should be fixed now

Thanks for the PR! Left some nits and questions but overall looks good to me.

[jychp]

added a small fix :

        ON CREATE SET
        u.firstseen = $UpdateTag
        ON MATCH SET u.user_id = user.id,
        u.agreed_to_terms = user.agreedToTerms,

ON MATCH SET will prevent data population on first run, replaced by SET

[achantavy]

Thank you for the PR!

Just gotta remove a whitespace and remove the on match set and I think the CI will pass

My bad I did not run pre-commit check localy after this small edit. Will fix lint and unit test tomorrow.
