In the RFC8693 token exchange, the CLI sends your access token and
receives in exchange a new cluster-scoped ID token.
Fix a bug in the CLI. Whenever the "pinniped login oidc" command was
planning to perform the RFC8693 token exchange, it failed to check if
the cached access token was still valid before performing the exchange,
which sends the access token. It instead checked if the cached ID token
was still valid, but that it not relevant in this situation because the
ID token is not going to be used for anything (instead the new ID token
returned by the RFC8693 token exchange will be used for auth).
This bug doesn't actually matter today, because the Supervisor-issued
access and ID tokens always both have the same 2-minute lifetimes.
However, future enhancements may cause them to have different lifetimes
in certain circumstances. Fixing this CLI bug now to prepare for those
potential future enhancements.
To make the subject of the downstream ID token more unique when
there are multiple IDPs. It is possible to define two IDPs in a
FederationDomain using the same identity provider CR, in which
case the only thing that would make the subject claim different
is adding the IDP display name into the values of the subject claim.
