The toolbox was not respecting the rook-config-override ConfigMap,
resulting in a minimal ceph.conf with only mon_host and keyring settings.
This made it difficult to run diagnostic commands that require custom
configuration parameters.
This change mounts the rook-config-override ConfigMap in all toolbox
variants and merges its contents into the generated ceph.conf. The
merge happens after writing the base config with mon endpoints, and
is re-applied whenever mon endpoints change.
The toolbox now has consistent behavior with other Rook-managed Ceph
daemons (mon, mgr, osd, mds, rgw) which already respect config overrides.
