10.0 | New CacheManager Extension

[llaville]

The new CacheManager extension will be in charge to handle properly the caching system.

That's includes :

• Cache Invalidation feature like Symfony Cache Component propose
• The lint command will "talk" to the CacheManager through the EventDispatcher
• The CacheManager will propose manual cache clearing via some new console commands added on fly
  • run phplint cache:clean console command to remove all cache entries from the cache directory, clearing it out entirely.
  • run phplint cache:prune console command to remove all unused cache entries.
  • run phplint cache:untag console command to remove cache entries from the cache directory, identified by a list of tags.

Depends on new Extension Architecture
