[PATCH] telemetry: promote experimental API to stable

[PATCH] telemetry: promote experimental API to stable

[Stephen Hemminger]

The remaining experimental telemetry functions have been present without
interface changes for several releases: the hexadecimal helpers
rte_tel_data_add_array_uint_hex() and rte_tel_data_add_dict_uint_hex()
since v23.03, and rte_telemetry_register_cmd_arg() since v24.11.
Promote all three to the stable ABI.
