The TestBootstrapClientServerRotation often fails because the reload
returns once the Server loop gets the new listener, but the server
hasn't really started yet. This commit makes the test pass, adding a
small sleep after the reload.
A proper fix might require a wrapper over the listener and an ACK
callback on a sync.Once on a custom Accept.

When step-ca runs with mTLS required on some endpoints, the SDK
used in autocert will fail to start because the identity certificate
is missing. This certificate is only required to retrieve all roots,
in most cases there's only one, and the SDK has access to it.
