need to handle missing units values in existing mongodb data

[Doug Hellmann]

The changeset that added meter units did not update the existing mongo database contents: https://review.openstack.org/#/c/18413/

It's a NoSQL db, do we really need to update all already stored documents?

[Doug Hellmann (doug-hellmann)]

We need to provide a units value, but I guess we could do that in the query. I'll change the description.

    Handle missing units values in mongodb data.

    Provide a units value if it's missing in the existing mongodb data. This
    is for the backward compatibility issue when the data had been already
    stored before the counter_unit field was added in our meter definition.

    Fixed bug #1098603.
