acl: gRPC login and logout endpoints (#12935)
Introduces two new public gRPC endpoints (`Login` and `Logout`) and
includes refactoring of the equivalent net/rpc endpoints to enable the
majority of logic to be reused (i.e. by extracting the `Binder` and
`TokenWriter` types).

This contains the OSS portions of the following enterprise commits:
