Fix: NAT44 deterministic moved to separate det44 plugin
- align CSIT code with VPP code changes for NAT44 deterministic (DET44) feature - align test names according to snat44ed tests - remove obsolete 3-node nat tests - remove 2n1l-10ge2p1x710-ethip4udp-snat44det-h1048576-p63-s66060288 tests (not enough memory for such high number of sessions) Change-Id: I9a22b99b4cfa56d18e9c7ef9c58296e202567d42 Signed-off-by: Jan Gelety <jgelety@cisco.com>
