It's an extremely common pattern in cephadm to need a triple of
(fsid, daemon_type, daemon_id). These triples are used to generate
various names and paths etc. Add a new type, DaemonIdentity, that
can represent these values in a more convient package. It has an
additional optional field "subcomponent" that can represent a
part of a daemon/service.
It is expected to be used in an immutable manner like a namedtuple,
but I didn't end using a namedtuple because cephadm doesn't make
much use of them and the syntax to combine namedtuple and type hints
is awkward.
