mgr/telemetry: handle daemons with complex ids

Treating daemons as `<daemon_type>.x` caused a crash
in the Telemetry module since the current method does not cover a case
where a daemon id is more complex, i.e. `<daemon_type>.x.y`.

When we parse the daemon type and daemon id, we should
split it into a maximum of two pieces rather than splitting
it by every `.` character. Specifying `1` in the Python
.split() function will limit the split to a maximum of two items.
