fix: add suboption for configuring execution order of tools

This could be accomplished by using wrapper scripts, but that would diminish
the usefulness of the incremental formatting logic. Configuring execution order
along with other things in the hgrc is probably more convenient anyway.

This change highlights some awkwardness with suboptions and default values,
which should be addressed separately.

Tests narrow stream clones

  $ . "$TESTDIR/narrow-library.sh"

#if tree
  $ cat << EOF >> $HGRCPATH
  > [experimental]
  > treemanifest = 1
  > EOF
#endif

Server setup

  $ hg init master
  $ cd master
  $ mkdir dir
  $ mkdir dir/src
  $ cd dir/src
  $ for x in `$TESTDIR/seq.py 20`; do echo $x > "f$x"; hg add "f$x"; hg commit -m "Commit src $x"; done

  $ cd ..
  $ mkdir tests
  $ cd tests
  $ for x in `$TESTDIR/seq.py 20`; do echo $x > "f$x"; hg add "f$x"; hg commit -m "Commit src $x"; done
  $ cd ../../..

Trying to stream clone when the server does not support it

  $ hg clone --narrow ssh://user@dummy/master narrow --noupdate --include "dir/src/f10" --stream
  streaming all changes
  remote: abort: server does not support narrow stream clones
  abort: pull failed on remote
  [255]

Enable stream clone on the server

  $ echo "[experimental]" >> master/.hg/hgrc
  $ echo "server.stream-narrow-clones=True" >> master/.hg/hgrc

Cloning a specific file when stream clone is supported

  $ hg clone --narrow ssh://user@dummy/master narrow --noupdate --include "dir/src/f10" --stream
  streaming all changes
  * files to transfer, * KB of data (glob)
  transferred * KB in * seconds (* */sec) (glob)

  $ cd narrow
  $ ls
  $ hg tracked
  I path:dir/src/f10

Making sure we have the correct set of requirements

  $ cat .hg/requires
  dotencode
  fncache
  generaldelta
  narrowhg-experimental
  revlogv1
  store
  treemanifest (tree !)

Making sure store has the required files

  $ ls .hg/store/
  00changelog.i
  00manifest.i
  data
  fncache
  meta (tree !)
  narrowspec
  undo
  undo.backupfiles
  undo.phaseroots

Checking that repository has all the required data and not broken

  $ hg verify
