> Avoid concurrent Catalog writes to Metastorage on the same node

> Project: Ignite

> Priority: Major

> Remaining Estimate: 0h

> Each DDL tries to make a write to the Metastorage. Each write is assigned a
> sequential number (version); if a few DDLs try to write to the Metastorage,
> they will all compete for the same version, and only one of them can succeed.
> This competition is wasteful. We need to avoid such concurrency on the same
> node by explicitly linearizing writes to the Metastorage from the Catalog
> before doing them.
