[PATCH] doc: announce removal of legacy telemetry

[Stephen Hemminger]

DPDK has carried two telemetry socket interfaces since 20.05: the
original legacy socket and the v2 socket that superseded it.

The legacy socket was kept only to support dpdk-telemetry-client.py,
which is its sole consumer. Everything it reports is available over the
v2 socket.

Announce removal of the legacy socket and the client script.
