Re-write the plugins

[zerodayz]

Yet again a new way of running the checks. To be compatible with containers and composable rules.

The idea is to run the independent checks per component/service.

An example workflow for mysqld tuning:

1. Check the logs for the mysqld running
2. If the previous check is true, then execute the tuning parameters check.

Right now the workflow is:

1. Check the node type
2. Run all the checks against that node.

No more we are checking for node type, actually we do all checks within the plugins script itself. All the checks are based on the author of the plugin script.
