Schema attribute of commit metadata should use table schema

In RFC 82 we found it is very hard to extract the table schema at a given point in time from historical completed instants. It is because they either does not write table schema when they tries to commit or they write the writer schema they use instead of table schema.

In RFC 82 we addressed the issue partially for OCC multi-writer case. For commits from table services,  single writer case and NBCC we also need to enforce this rule
