Description of problem:

The namespace is Mandatory now. which is not correct.

when user isn't cluster-admin,  kubernetes_namespace_name is Mandatory. the query should include all namespaces. For example:

logcli -o raw --bearer-token="${bearer_token}" --tls-skip-verify --addr="https://${lokistack_route}/api/logs/v1/application" query --limit=1 '{log_type="application",kubernetes_namespace_name=~"app-testuser-1|test-log-user1-1706711817"}' 

when user is cluster-admin,   kubernetes_namespace_name is not Mandatory. we can ignore  namespace or fill in all supported namespaces.

Actual results:

Expected results:

The user can query cross all namespaces.
