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 #171)

Started with some ideas on how to perform the testing per plugin with a mock-up here: https://github.com/tonyskapunk/recap/commit/5ee9235ecfe54fc4ccd4cc1db0c94fb983a41b20
