resolves: flanksource/mission-control#1378

When the kratos client makes call to any admin endpoints (eg: updating traits of identities), it requires the admin url. If not provided it uses the kratos api URL with port 4434.

"https://kratos-6c96d4c97f-p7rq2:4434/admin/identities/5146f95d-0180-43c5-bc43-92460d3b021e\": dial tcp: lookup kratos-6c96d4c97f-p7rq2 on 172.20.0.10:53: no such host

Setting the admin base_url solves this.
