This is a backport of #173 to
release/vault-1.11.x
. It also pulls in #162 since we need to test/build with go-1.19.Previously, it was possible for the http.Client's Transport to be missing the necessary root CAs to ensure that all TLS connections between the auth engine and the Kubernetes API were validated against a configured set of CA certificates.
This fix ensures that the http.Client's Transport is always consistent with the configured CA cert chain, by introducing a periodic TLS configuration checker that is started as part of the backend's initialization.
