Stanislau Hlebik 7dc24c7c82 infinitepush: backup local heads and bookmarks 
Summary:
Backuping changesets is not enougn for restore. We also want to backup heads
and bookmarks to completely capture the state of the repo.

This diff is the first step in implementing this functionality. It adds new
bundle2 part which contains encoded dict (simple json encoding is used).
If value in the dict is empty then key is the bookmark pattern to delete.
If value is not empty then key is the bookmark name to save and value is a
node hash. The reason to put them in the same part is to make it possible to
delete and insert into indexapi in one transaction. It's also possible to pass
patterns to delete in part parameters but there is a bug in upstream hg that
limits parameters' size to 256 and we can potentially have longer bookmarks.

Local bookmarks are saved in infinitepush in the following form:
  infinitepush/backups/USERNAME/HOSTNAME/REPOROOT/bookmarks/LOCAL_BOOKMARK_NAME

Local heads are saved in infintiepush in the following form:
  infinitepush/backups/USERNAME/HOSTNAME/REPOROOTheads/HEAD_HASH

Hostname, username and repo root is necessary to distinguish different backups.

Test Plan: Run `test-infinitepush-*`

## What is it?

This extension adds ability to save certain pushes to a remote blob store
as bundles and to serve commits from remote blob store.
The revisions are stored on disk or in everstore.
The metadata are stored in sql or on disk.

## Config options

infinitepush.branchpattern: pattern to detect a scratchbranch, example
                            're:scratch/.+'

infinitepush.indextype: disk or sql for the metadata
infinitepush.reponame: only relevant for sql metadata backend, reponame to put in
                       sql

infinitepush.indexpath: only relevant for ondisk metadata backend, the path to
                        store the index on disk. If not set will be under .hg
                        in a folder named filebundlestore

infinitepush.storepath: only relevant for ondisk metadata backend, the path to
                        store the bundles. If not set, it will be
                        .hg/filebundlestore
