h1. Federated identity

A person should be able to create an account and get a token from a single identity provider, and use that token to access private/protected resources on multiple Arvados clusters.

Motivating use cases:
6
* A user on cluster B shares a project with a user on cluster A.
7
* A container running on cluster A reads and writes data on cluster B.
8
* A user logged in to Workbench A can search/view/download/upload collections at cluster B.

Configuration examples:
11
* An organization has 5 clusters, but only one of them has user accounts and roles in its database.
12
* An on-premise cluster runs containers that use public data stored in the cloud (without mirroring the data locally).

Each Arvados client must be able to prove to cluster B that it is authorized by cluster A to act on behalf of a user account which is controlled by cluster A. This must not involve giving enough information to cluster B to act on behalf of the user account: for example, the client cannot simply give cluster B its cluster A token for the purpose of doing a canary query.
