Introduces a [capi_helm_cluster_labels] oslo.config group that serves
as the authoritative registry for all supported cluster labels. Each
label is defined as a typed oslo.config option (BoolOpt/IntOpt/StrOpt)
with a default value and help text, which operators can override
site-wide in magnum.conf and users can override per-cluster via
Magnum labels.
The five csi_cinder_* options previously scattered in [capi_helm] are
migrated to the new group with deprecated_opts so existing magnum.conf
files remain compatible without changes.
_label(), _get_label_bool(), _get_label_int() now raise ValueError for
any key not registered in the new group. A new _get_label_csv() method
handles the comma-separated api_master_lb_allowed_cidrs label.
A new AST-based unit test (TestClusterLabelRegistry) walks driver.py
at test time and asserts that every string-literal key passed to any
_label* method is present in capi_helm_cluster_labels_opts, preventing
unregistered labels from being silently introduced.
Documentation is updated to drop the hand-maintained label table in
favour of a cross-reference to the Configuration Reference page, which
oslo_config.sphinxext now auto-generates from the new group alongside
the existing [capi_helm] section.
