KV watch multiple filters

[Jarema]

Overview

KV watch supports only single filter, which has limitations similar to those of single filter consumers.

Clients should support kv::watch watching multiple filters, leveraging consumers with multiple filters.

That can be a separate method (for example watch_many), or extension to the current one, depending on the language and it's ability to introduce multiple KV watch filters without breaking changes.
