upgrade: implement partial upgrade for upgrading persistent-nodemap

Upgrading repositories to use persistent nodemap should be fast and easy as it
requires only two things:

1) Updating the requirements
2) Writing a persistent-nodemap on disk

For both of the steps above, we don't need to edit existing revlogs.

This patch makes upgrade only do the above mentioned two steps if we are
only upgarding to use persistent-nodemap feature.

Since `nodemap.persist_nodemap()` assumes that there exists a nodemap file for
the given revlog if we are trying to call it, this patch adds `force` argument
to create a file if does not exist which is true in our upgrade case.

The test changes demonstrate that we no longer write nodemap files for manifest
after upgrade which I think is desirable.

## 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
