clone-bundles: introduce a command to refresh bundle

This command allows for a different mode than the one attached to the
transation. It might fit some hosting setup better.

#require no-reposimplestore no-chg

Test bundles are generated on push

Test conditions to get them generated
=====================================

Check ratio

  $ cat >> ../server/.hg/hgrc << EOF
  > [clone-bundles]
  > trigger.below-bundled-ratio = 0.5
  > EOF

  full-v2-6_revs-b1010e95ea00_tip-*_txn.hg (glob)
  $ ls -1 ../server/.hg/tmp-bundles

Check absolute number of revisions

  $ cat >> ../server/.hg/hgrc << EOF
  > [clone-bundles]
  > trigger.revs = 2
  > EOF
  $ touch bur

Test generation through the dedicated command
=============================================

  $ cat >> ../server/.hg/hgrc << EOF
  > [clone-bundles]
  > auto-generate.on-change = no
  > EOF

Check the command can generate content when needed
--------------------------------------------------

Do a push that makes the condition fulfilled,
Yet it should not automatically generate a bundle with
"auto-generate.on-change" not set.

  $ touch quoi
  $ hg -q commit -A -m 'add quoi'

  $ pre_push_manifest=`cat ../server/.hg/clonebundles.manifest|f --sha256 | sed 's/.*=//' | cat`
  $ pre_push_upload=`ls -1 ../final-upload|f --sha256 | sed 's/.*=//' | cat`
  $ ls -1 ../server/.hg/tmp-bundles

  $ hg push
  pushing to $TESTTMP/server

  adding file changes
  added 1 changesets with 1 changes to 1 files

  $ post_push_manifest=`cat ../server/.hg/clonebundles.manifest|f --sha256 | sed 's/.*=//' | cat`
  $ post_push_upload=`ls -1 ../final-upload|f --sha256 | sed 's/.*=//' | cat`
  $ ls -1 ../server/.hg/tmp-bundles
  $ test "$pre_push_manifest" = "$post_push_manifest"
  $ test "$pre_push_upload" = "$post_push_upload"

Running the command should detect the stale bundles, and do the full automatic
generation logic.

  $ hg -R ../server/ admin::clone-bundles-refresh
  clone-bundles: deleting bundle full-v2-6_revs-b1010e95ea00_tip-*_txn.hg (glob)

  full-v2-8_revs-8353e8af1306_tip-*_txn.hg (glob)
  $ ls -1 ../server/.hg/tmp-bundles

Check the command cleans up older bundles when possible
-------------------------------------------------------

  $ hg -R ../server/ admin::clone-bundles-refresh
  clone-bundles: deleting bundle full-v2-8_revs-8353e8af1306_tip-*_txn.hg (glob)

  $ ls -1 ../final-upload
  full-v2-10_revs-3b6f57f17d70_tip-*_acbr.hg (glob)
  $ ls -1 ../server/.hg/tmp-bundles

Nothing is generated when the bundles are sufficiently up to date
