Subject: mgr/dashboard: fetch all namespaces in a gateway group
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=refs%2Fpull%2F67101%2Fhead;p=ceph.git

mgr/dashboard: fetch all namespaces in a gateway group

- adds a new API /api/gateway_group/{group}/namespace
- updates tests
- needed for UI flows and in general to fetch all namespaces, could not change existing API due to the maintenence of backward compatibility
- in a followup PR will add server side pagination

Fixes https://tracker.ceph.com/issues/74622
