tests: L3, L4 and VxLAN tests for OVS & VPP

A set of tests was introduced with focus on L3, L4 and VxLAN performance
of OVS and VPP. New testcases were created for phy2phy network scenario.
In case of PVP and PVVP, only OVS testcases are available.

Notes:
* two sets of OVS P2P testcases were created, one creates unique flow
  for each IP address involved in the test (performance sensitive);
  Second set inserts just one flow with large network mask (tests with
  _mask suffix).
* three different types of VPP P2P L3 testcases were created to
  demonstrate performance impact of multi ARP entries or IP routes.
* VPP multi ARP record based testcases use a set of "workarounds"
  to load a large number of ARP entries. It is not possible to use
  "set ip arp count" syntax, as it doesn't work well for large count
  values (e.g. 60K)
* OVS VxLAN testcases utilize existing OP2P deployment scenario and thus
  it can be used also with GRE and GENEVE tunnel types. Tunnel type
  to be used is defined by test configuration option "Tunnel Type".

+#   1) unique rule for each IP stream (OVS only)
+#   2) one rule for /8 netmask covering all streams
+#   3) unique ARP entry for each IP stream (VPP only)
+#   4) unique IP route for each IP stream (VPP only)
