Tests separation

[tonyskapunk]

For testing purposes it would be good to separate them in:

• Test core reports
• Test plugin reports
  • When there is no service enabled, e.g. http, redis, docker, etc.
  • When the service is enabled (as expected)

Plugins:

• redis
• docker_top
• kernel_cmd
• http_status (pending in Make http_status (USEFULLSTATUS) a plugin #171)

Started with some ideas on how to perform the testing per plugin with a mock-up here: tonyskapunk@5ee9235
