contrib: move the `discovery-helper.sh` script in`perf-utils` directory

The script appeared before the directory. However the directory exists for this
kind of script. We move it there.

-# The Goal is to produce two repositories with some common part and some
-# exclusive part on each side. Provide a source repository REPO, it will
-# produce two repositories REPO-left and REPO-right.
-#
-# Each repository will be missing some revisions exclusive to NBHEADS of the
-# repo topological heads. These heads and revisions exclusive to them (up to
-# DEPTH depth) are stripped.
-#
-# The "left" repository will use the NBHEADS first heads (sorted by
-# description). The "right" use the last NBHEADS one.
-#
-# To find out how many topological heads a repo has, use:
-#
-#   $ hg heads -t -T '{rev}\n' | wc -l
-#
-# Example:
-#
-#  The `pypy-2018-09-01` repository has 192 heads. To produce two repositories
-#  with 92 common heads and ~50 exclusive heads on each side.
