colflow: do not set redundant tag on the tracing span
This is unnecessary given that we're setting the componentID below that
includes the flowID.
Release justification: low-risk update to new functionality.
Release note: None
tracing: do not set tags when setting stats
We no longer need to set tags on the tracing span in order to propagate
stats since we now propagate that info as a whole object (at the moment,
twice - as a Structured payload and as DeprecatedStats protobuf; the
latter will be removed after 21.1 branch is cut).
Addresses: #59379.
Release justification: low-risk update to new functionality.
Release note: None
