This patch adds the telemetry UNIX socket. It is used to
allow connections from external clients.
On the initial connection from a client, ethdev stats are
registered in the metrics library, to allow for their retrieval

Introduced DEV_TX_OFFLOAD_OUTER_UDP_CKSUM offload flags and
PKT_TX_OUTER_UDP_CKSUM mbuf ol_flags to enable Tx outer UDP

To use hardware Tx outer UDP checksum offload, the user needs to,

a) fill outer_l2_len and outer_l3_len in mbuf
b) set the PKT_TX_O
Introduced DEV_RX_OFFLOAD_OUTER_UDP_CKSUM Rx offload flag and
