Find a way to make Locksmith work better while bootstrapping. Polling like this is pretty fucked up. Maybe there should be a proper "Consul is ready without SMT" level and Locksmith and the Chant Listener should be configured to work with that level.

Setting the default token means it's no longer required to present a token when connecting to this agent. Should probably limit this to automatic actions only (dns, replication token types?)

This should definitely be statically optional, i.e. can disable ACL support in this module.

This should probably be dynamically optional, i.e. check for the existence of the token file first. This could be useful for registering and/or running distributed Consul services before the ACL bootstrap is complete.
