Seemed wise to upgrade before we do even more with JWTs. For example
this upgrade *would* have mattered if we already implemented common JWT
claims such as expiration. Since we didn't rely on any claim
verification this upgrade is a noop...
...except for 1 test that called `Claims.Valid()`! Removing that
assertion *seems* scary, but it didn't actually do anything because we
didn't implement any of the standard claims it validated:
https://github.com/golang-jwt/jwt/blob/v4.5.0/map_claims.go#L120-L151
So functionally this major upgrade is a noop.
The OIDC provider cache is used by the RPC handler as the OIDC
implementation keeps long lived processes running. These process
include connections to the remote OIDC provider.
The Callback server is used by the CLI and starts when the login
command is triggered. This callback server includes success HTML
which is displayed when the user successfully logs into the remote
OIDC provider.
