Perf: NAT44 endpoint-dependent mode - udp, part I

- continuation of https://gerrit.fd.io/r/c/csit/+/26898 as there was
reached limit of changes (1000)

Jira: CSIT-1711

- udp synthetic profiles w/o data packets
- udp cps perf tests, phase I (no special "search cps" KW)

Part I means that we are using MRR tests to collect traffic data
until there is ready new CPS test type with corresponding algorithm.
