Update by Query

[etiennedi]

Describe your feature request

In #2124, an update by query is mentioned as a "second, less important" idea. This ticket is to split this out into a separate ticket, so #2124 can focus exclusively on "Batch Patch".

For this one we envision a feature that behaves like update table set col1='foo' where x=true in SQL. Or in Weaviate terms, it would behave like "batch delete" in the sense that it takes in a where filter. But instead of deleting it would apply the specified patch to all matches.
