hubble/parser: Do not warn about missing identities
hubble/parser: Do not warn about missing identities

This commit is intended to make Hubble more usable when Cilium is
running in LB-only mode.

Identity lookup in the Hubble parser might fail for various reasons, for
example, when running in the LB-datapath mode. Since the user cannot do
anything about this (and the absent data is still detectable via Hubble
API), stop emitting a warning in the logs and use a debug statement
instead.
