[BUG]Pagination is not working for List namespaces

[shraddhagrawal]

Is this a possible security vulnerability?

• This is NOT a possible security vulnerability

Describe the bug

Even if we specify page size api is returning all namespaces
In docs it is mentioned "servers that support pagination" can you please elaborate what this means?

To Reproduce

curl --location 'http://localhost:8181/api/catalog/v1/polaris/namespaces?parent=accounting&pageSize=1&pageToken=null'
--header 'Authorization: Bearer principal:root;password:xxxxxxxxxxxxxxxx;realm:default-realm;role:ALL'
--data ''

Actual Behavior

returned all namespaces

Expected Behavior

return only one namespace

Additional context

System information

Polaris doesn't support pagination yet in my understanding. You can see pageToken and pageSize parameters are unused:
