strip: remove experimental.prunestrip option

marmoute decided to drop it because it's "neither documented nor a good idea".

This extensions was assemble to deal with Facebook willingness to check `hg
strip` semantic for its user. Changing `hg strip` semantic is overall a pretty
bad idea, because `stripping` is a specific operation, that is problematic in
distributed version control but have a narrow set of valid usecase (eg:
maintenance). Diverting user away from `prune` in favor of a modified `strip` is
a bad idea, because it mask the legitimate `strip` usage and introduce confusion
in user heads, The verb is not appropriate and the behavior of `prunestrip` does
not match the one of vanillia `strip`.

Facebook is no longer using this, and the lack of documentation is a good hint
that nobody else is. So lets drop it.

====================================
Testing head checking code: Case E-2
====================================

Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.

This case is part of a series of tests checking this behavior.

Category F: case involving changeset on multiple branch
TestCase 2: moving interleaved branch away from each other

Test setup
----------

  $ mkdir E1
  $ cd E1
  $ setuprepos
  creating basic server and client repo
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd client
  $ hg topic -r . Y
  switching to topic Y
  changed topic on 1 changesets to "Y"
  $ hg strip --config extensions.strip= --hidden 'hidden()' # clean old A0
  saved backup bundle to $TESTTMP/E1/client/.hg/strip-backup/8aaa48160adc-19166392-backup.hg
  $ hg topic Z
  $ mkcommit B0
  active topic 'Z' grew its first changeset
  (see 'hg help topics' for more information)
  $ hg topic Y
  $ mkcommit C0
  $ hg push
  pushing to $TESTTMP/E1/server
  searching for changes
  adding changesets
  adding manifests
  adding file changes
  added 3 changesets with 2 changes to 3 files (+1 heads)
  1 new obsolescence markers
  obsoleted 1 changesets
  $ hg up 0
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  $ hg topic Y
  marked working directory as topic: Y
  $ mkcommit A1
  $ mkcommit C1
