This commit allows constant propagation of connection secrets from managed
resources to their bound resource claims. It does this by updating the existing
APIManagedConnectionPropagator to add 'propagation annotations', which can be
used by a new 'secret propagating reconciler' to watch both secrets for constant
propagation. The predicates and enqueue handler required to implement this are
included.
