No need at all to use a different puppet master, you could just use
environments[1]. When you want to test a system again a different
environment, staging in this example, you can run `puppet agent -t
--environment=staging`.

Hiera[2] is meant to solve this. You might have staging.yaml and
production.yaml that specify values for mysql_innodb_buffer_pool_size.
In your code you could have
$innodb_buffer_pool_size = hiera('mysql_innodb_buffer_pool_size')
and then use <%= innodb_buffer_pool_size %> in a template for your my.cnf.
