[pulsaradmin] Add GetAllSchemas command

calindima commented 1 month ago

Didn't create an issue but I can if that's necessary, otherwise I'll write the details in this PR.

Motivation

Explain here the context, and why you're making that change. What is the problem you're trying to solve.

We actively use pulsarctl which has a dependency on this library. We have a use case where we want to interogate the SchemaRegistry to retrieve a history of schema versions and observe schema evolution for topics with higher retention (e.g. infinite retention, >6mo retention etc.).

Thanks for running the workflows @crossoverJie. I fixed the linter error but the failed integration test is not related to anything changed in this PR as far as I can tell.
