bq. Isn't that also true for Approach 1, just that we'd have to put the tokens
into a store owned by the collector instead of the RM?
No. We do not have state store for managed apps in approach 1. Tokens are
regenerated upon restart and passed onto AM along with collector address(which
also changes upon restart).
