Leverage dpdk_conf to set configuration flag RTE_HAVE_JANSSON when Jansson dependency is found. 2. In rte_metrics_telemetry.c, leverage RTE_HAVE_JANSSON to handle the case when JANSSON is not available by adding stubs for all the instances. 3. In meson.build, per dpdk\doc\guides\rel_notes\release_20_05.rst, it is claimed that "Telemetry library is no longer dependent on the external Jansson library, which allows Telemetry be enabled by default.", thus make the deps and includes of Telemetry as not conditional anymore.
