Add support for Organizations [SDK-2398]

[lbalmaceda]

Changes

This PR adds support for organizations. It consists of two new setters added to the webauth module.

Accept an invitation to join an organization

Pass the invitationUrl parameter to the webAuth.authorize method to allow the user to accept an invitation. The given URL will be parsed and the required values extracted and used when the browser is launched.

Log in to an organization

If the organization ID is known, pass the organization parameter to the webAuth.authorize method to allow the user to log in to an organization.

When logging in into an organization, the received ID token will contain an org_id claim that will be automatically verified against the organization id requested when the authentication was started.
