infinitepush: introduce server option to route every push to bundlestore

This patch introduces a new config option for server
`infinitepush.pushtobundlestore` which if sets to True, the server will route
each incoming push to the bundlestore and store all the parts i.e. changegroups,
phases, obsmarkers in the bundlestore and won't be applied to the revlog.

This config option does not need any client side wrapping and does not need any
custom bundle2 part or stream level parameter to decide where the push should
go.

This is very useful for Mozilla CI use case where they have a central server
that recieves pushes to trigger code-reviews, trigger a test run of CI, run
static analysis etc. The server using the new config option can stash standalone
bundles to the bundlestore and server can get access to individual revisions on
demand.

A new test file which has related tests are added for the config option.

Differential Revision: https://phab.mercurial-scm.org/D2958

In this test, we want to test LFS bundle application on both LFS and non-LFS
repos.

To make it more interesting, the file revisions will contain hg filelog
metadata ('\1\n'). The bundle will have 1 file revision overlapping with the
destination repo.

#  rev      1          2         3
#  repo:    yes        yes       no
#  bundle:  no (base)  yes       yes (deltabase: 2 if possible)

It is interesting because rev 2 could have been stored as LFS in the repo, and
non-LFS in the bundle; or vice-versa.

Generate bundles

  $ for i in normal lfs; do
  >   NAME=src-$i
  >   hg init $TESTTMP/$NAME
  >   cd $TESTTMP/$NAME
  >   [ $i = lfs ] && enablelfs
  >   commitxy
  >   commitz
  >   hg bundle -q --base X -r Y+Z $TESTTMP/$NAME.bundle
  >   SRCNAMES="$SRCNAMES $NAME"
  > done

Prepare destination repos

  $ for i in normal lfs; do
  >   NAME=dst-$i
  >   hg init $TESTTMP/$NAME
  >   cd $TESTTMP/$NAME
  >   [ $i = lfs ] && enablelfs
  >   commitxy
  >   DSTNAMES="$DSTNAMES $NAME"
  > done

Apply bundles

  $ for i in $SRCNAMES; do
  >   for j in $DSTNAMES; do
  >     echo ---- Applying $i.bundle to $j ----
  >     cp -R $TESTTMP/$j $TESTTMP/tmp-$i-$j
  >     cd $TESTTMP/tmp-$i-$j
  >     if hg unbundle $TESTTMP/$i.bundle -q 2>/dev/null; then
  >       hg verify -q && echo OK
  >     else
  >       echo CRASHED
  >     fi
  >   done
  > done
