discovery: new devel.discovery.randomize option

By default, this is True, but setting it to False is a uniform
way to kill all randomness in integration tests such as test-setdiscovery.t

By "uniform" we mean that it can be passed to implementations in other
languages, for which the monkey-patching of random.sample would be
irrelevant.

In the above mentioned test file, we use it right away,
replacing the adhoc extension that had the same purpose, and to derandomize a
case with many round-trips, that we'll need to behave uniformly in the Rust
version.

check whether HG_PENDING makes pending changes only in relatd
repositories visible to an external hook.

In "hg share" case, another transaction can't run in other
repositories sharing same source repository, because starting
transaction requires locking store of source repository.

Therefore, this test scenario ignores checking visibility of
.hg/bookmarks.pending in repo2, which shares repo1 without bookmarks.

  $ cat > $TESTTMP/checkbookmarks.sh <<EOF
  > echo "@repo1"
  > hg -R "$TESTTMP/repo1" bookmarks
  > echo "@repo2"
  > hg -R "$TESTTMP/repo2" bookmarks
  > echo "@repo3"
  > hg -R "$TESTTMP/repo3" bookmarks
  > exit 1 # to avoid adding new bookmark for subsequent tests
  > EOF

FYI, in contrast to above test, bmX is invisible in repo1 (= shared
src), because (1) HG_PENDING refers only repo3 and (2)
"bookmarks.pending" is written only into repo3.

  $ cd ../repo3
  $ hg --config hooks.pretxnclose="sh $TESTTMP/checkbookmarks.sh" -q book bmX

same as bm3 in the svfs case)
