vcl: add support for app socket api
To enable add "app-socket-api /path/to/socket" to vcl.conf. On vpp side, add use-app-socket-api to session stanza in startup.conf VPP allocates a socket per application namespace which it places in the app_ns_sockets subfolder of the run folder (default /var/run/vpp). The socket used implicitly selects the app namespace for the vcl app. Type: feature Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: Ifc14b93dcbf6ef9bed1852d46cd069f4855b92ef
