Merge Ceph configs into global.yaml after Ceph setup

bootstrap.sh reads global.yaml directly and does not source odf.sh,
so quayBackendRGWConfiguration and odfExternalConfig must be in
global.yaml for the validate and operators steps to work.

Append both configs on the LZ side via a remote script to avoid
shell quoting issues with the JSON content.
