as the support for external CAs is more mature than external discovery servers. This supports some additional
configuration, a `CredentialFetcher` which allows fetching a token from places other than a file (for example, a local
metadata server), and a `TokenExchanger` which allows exchanging a token for another form to match the CA server requirements.

For VMs, the standard flow is for the user to provision a short-lived JWT token onto the VM. After the initial

* Metadata Agent Improvements ([#66485](https://github.com/kubernetes/kubernetes/pull/66485), [@bmoyles0117](https://github.com/bmoyles0117))
    * Bump metadata agent version to 0.2-0.0.21-1.
    * Expand the metadata agent's access to all API groups.
    * Remove metadata agent config maps in favor of command line flags.
    * Update the metadata agent's liveness probe to a new /healthz handler.
