 Description   

MariaDB startup does not validate plugin-wsrep-provider when wsrep_on=off or wsrep_provider is not set.
Server should not allow to set new variable plugin-wsrep-provider if wsrep_on==off or when wsrep_provider is not set.

Fixed on branch : preview-10.11-MDEV-22570-wsrep-provider-options-plugin

I try to do test case but it seems hard as server will not start.
