Listen to cache:flush events

- if magerun cache:flush runs
- if admin is pressing on "flush magento cache"
- if admin is pressing on "flush cache storage"

Then the DI container files should be removed accordingly.
This also fixes a bug when during capistrano deployments, the container were not cleaned up (as 99% of times only magerun cache:flush is called)
