when is to support  `databaseinitsql`? 

it is that user can use custorm initsql by `databaseinitsql`
in doc  https://github.com/radondb/radondb-mysql-kubernetes/blob/main/docs/crd_mysqlcluster_v1beta1.md#databaseinitsql 

but after review code , there is not support right now, 

so is there  a plan ?

thanks
