What is the purpose?
Store token and later retrieve Authentication object from access token.
What is default tokenStore?
When there is AuthorizationServer:
Don't use remote resource token. it's InMemoryToken store.
It's not a bean. It's created directly by new operator in AuthorizationServerEndpointCOnfigure
When there is only ResourceServer, it needs Jwt/Jwk configure.
Default config use RemoteTokenService implemenst ResourceServerTokenServices (seems to be no token store at local)
