get bucket endpoint with a limit over 100 results returns an error

Executing a request to get all of the existing buckets with a `limit` parameter over 100 returns an error.
The error says that `limit` should be between `1` and `100`, but swagger doc does not mention this limitation.
Unless there is a requirement to limit the number of results to 100 (not sure why would we want that), we should remove the limitation,

Start by reproducing the get-buckets request with a limit over 100 and inspect the endpoint's validation alongside its Swagger documentation. Determine whether the 100-result cap is required; done means either larger limits work or the restriction and its documented rationale are consistent.
