We need to keep the old name for better integration with previous tools we had.
[Core] Kernel's boot method shouldn't return booted level

On KernelInterface there is no documentation that boot returns booted level,
therefore should be removed and since we need this, we added an extra method
to get it, if needed.

[Core] Kernel's boot method shouldn't return booted level
[Core] Kernel failure should only happen when no boot level was reached

Kernel failure shouldn't be happening on any boot level failure. For that there
will be other levels/events that should be added.

[Core] Kernel failure should only happen when no boot level was reached
[Core] Improve Kernel events to allow boot level events later

Kernel verbosity is level `VERBOSITY_VERY_VERBOSE`:
http://symfony.com/doc/current/components/console/introduction.html#verbosity-levels
We will spare `VERBOSITY_DEBUG` to boot level events that will explain
in more detail what is happening at each boot level.
[Core] Create boot level events

This creates a structure that will allow the boot levels logic to be outside
the Kernel. Furthermore it allows extensions by simply subscribing to these
events and make custom logic to accept that a certain boot level was reached.

If later we allow custom bootstrap levels, this will support it a lot easier.

Suport Sugar versions as a proxy for the Kernel

This provides a Sugar\Manager that will make use of a Sugar\Finder\Finder to
find a sugar based on a given path.
Sugar\Manager will give you a proxy so that you can mock all Sugar calls based
on their versions. This will allow us to work faster providing just the changes
of each version and keep the same functionality on the commands (being version
agnostic as much as possible).
Keep in mind that you can still check for the Sugar Version to make special
cases on your commands.
