hsa: add http throughput test server app
Can be used for throughput testing over http. For instance, start server: http tps #implicitly listens on port 80 Then, to test throughput with curl: curl <server_ip>/test_file_10g curl <server_ip>/test_file_123m Similarly, for https: http tps uri tls://<server_ip>/443 curl -k <server_ip>/test_file_1g Type: feature Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I30ab7f0d94a7357b3f04546e4a3d3c410a733908
