add props in ShardAllocationDoc

[AmitPhulera]

I got the following error while trying to replicate data to new nodes in backup production env while ran plan for the migration.

Traceback (most recent call last):
  File "jsonobject/base.pyx", line 202, in jsonobject.base.JsonObjectBase.__init__
  File "jsonobject/base.pyx", line 239, in jsonobject.base.JsonObjectBase.set_raw_value
  File "jsonobject/base.pyx", line 322, in jsonobject.base.JsonObjectBase.__setattr__
AttributeError: 'props' is not defined in schema (not a valid property)

During handling of the above exception, another exception occurred:

This is a new property that is available in all the new dbs that are created, the usage is not documented but found a reference in https://docs.couchdb.org/en/stable/partitioned-dbs/index.html\#partitions-by-example.

The issue in coming in commcarehq__users-tmp db that was newly created in couchdb 3.x.
