parameters.yml and pdo_mysql

[sosek108]

During first initialization composer asks for database engine (default: pdo_sqlite) but if you change it for 'pdo_mysql' it doesn't ask for information about MySQL server.

You can create by yourself information about server in parameters.yml but they're overriden (deleted) after another composer action.

You can only change info in 'config.yml' but it's not as 'user-friendly' as using 'parameters.yml'

I agree.

@wouterj I think we should match the core SE there too
