repmam: Databases are added to cluster by requesting slave instances 

To add a Database, user should request a slave instance. Each slave
instance is a database.

- Destroy slave database if slave instance was destroyed

- Update and remove slave database only on master mariadb

- Allow to create database slave with character sets and collate options

- Generate slave database password if not set
