Add the per data center DC-DR view to MariaDB status, mirroring the Postgres shape. A distributed MariaDB is expanded into one self contained Galera cluster per Member DC; the cross-DC active DC decision is owned by the dr-controlplane primary-DC Lease and reflected here on the single Database object. MariaDBDisasterRecoveryStatus carries the active DC, the DR phase, and a per-DC view (role, representative node, writable, cross-DC async lag, health). MariaDBDCStatus is one DC's local view.

A distributed DC-DR MariaDB has one intra-DC Galera quorum per data center, each scaled independently. Add MariaDBHorizontalScalingDC and a dataCenters list on MariaDBHorizontalScalingSpec so an ops request can set per data center local node counts instead of the single cluster wide member count. Regenerate the ops CRD. Signed-off-by: Tamal Saha <tamal@appscode.com>

Adapts the Postgres DC-DR API work to MariaDB (a quorum based, multi-primary Galera engine). A distributed MariaDB is expanded by the operator into one self contained Galera cluster per Member data center; the cross-DC active DC decision is owned by the dr-controlplane primary-DC Lease and reflected on the single Database object.
Changes
apis/kubedb/v1/mariadb_types.go: addstatus.disasterRecovery(MariaDBDisasterRecoveryStatus,MariaDBDCStatus,MariaDBDRPhase{Steady,FailingOver,FailingBack,Degraded}). Per-DC view carries role, representative Galera node, writable, cross-DC async lag bytes, and health.apis/ops/v1alpha1/mariadb_ops_types.go: addMariaDBHorizontalScalingDCand adataCenterslist onMariaDBHorizontalScalingSpecso an ops request scales each DC's intra-DC Galera quorum independently.Mirrors the merged/in-flight Postgres DC-DR types. Dependent repos (mariadb operator, mariadb-coordinator) bump to this once released.
