Add test suites for crypto sw scheduler engine

This patch is to add test suites for vpp plugin crypto_sw_scheduler,
IPsec sync mode is to do crypto and packet forward work in same worker cores,
crypto_sw_scheduler can schedule crypto work to other async crypto cores to
improve whole crypto processing capability.

This test suites configure fixed 1 rx queues per port, then measure IPsec
performance with 1, 2, 3 crypto cores.

This patchset include 1, 2, 4, 8 ipsec tunnels test cases.

+Vratko help to change to count total physical cores instead of previous only
count crypto cores in test cases.
