REST: Add support for page-size in list_namespaces, list_tables, and list_views

[ebyhr]

Rationale for this change

Follows REST catalog spec:

• /v1/{prefix}/views: https://github.com/apache/iceberg/blob/e7a5a87f26f9de5b200254155aa037368b13a29c/open-api/rest-catalog-open-api.yaml#L1525-L1538
• page-size: https://github.com/apache/iceberg/blob/e7a5a87f26f9de5b200254155aa037368b13a29c/open-api/rest-catalog-open-api.yaml#L2029-L2038

Are these changes tested?

Yes.

Are there any user-facing changes?

Add support for page-size in list_views in REST catalog.

LGTM

now that list_namespace (#3347), list_tables (#3348) and list_views (#3349) are all merged, could we use this PR to add support for page-size for all of them?

Suggested change

	params = {}
	page_size = property_as_int(self.properties, PAGE_SIZE, None)
	if page_size is not None:
	if page_size <= 0:
	raise ValueError(f"{PAGE_SIZE} must be a positive integer")
	params["pageSize"] = str(page_size)
	page_size = property_as_int(self.properties, PAGE_SIZE, None)
	if page_size is not None and page_size <= 0:
	raise ValueError(f"{PAGE_SIZE} must be a positive integer")

Suggested change

	if page_token:
	params["pageToken"] = page_token
	params: dict[str, str] = {}
	if page_size is not None:
	params["pageSize"] = str(page_size)
	if page_token:
	params["pageToken"] = page_token

nit: follows the same pattern as list_namespaces (#3347) and list_tables (#3348)

The page size remains constant throughout the while loop, unlike the page token. That is why I set the value outside the loop.

Let me know if you still want me to commit this suggestion.
