This patch entirely removes the ioam selftests to prepare for the next
patch in this series, which re-adds the new ioam selftests for better
readability.

-# This script evaluates the IOAM insertion for IPv6 by checking the IOAM data
-# consistency directly inside packets on the receiver side. Tests are divided
-# into three categories: OUTPUT (evaluates the IOAM processing by the sender),
-# INPUT (evaluates the IOAM processing by a receiver) and GLOBAL (evaluates
-# wider use cases that do not fall into the other two categories). Both OUTPUT
-# and INPUT tests only use a two-node topology (alpha and beta), while GLOBAL
-# tests use the entire three-node topology (alpha, beta, gamma). Each test is
-# documented inside its own handler in the code below.
-#
-# An IOAM domain is configured from Alpha to Gamma but not on the reverse path.
-# When either Beta or Gamma is the destination (depending on the test category),
-# Alpha adds an IOAM option (Pre-allocated Trace) inside a Hop-by-hop.
