Clean up Phalcon\DiInterface

[ghost]

!!! The below affects only Phalcon\DiInterface, no changes were made to Phalcon\DI itself.

• Remove setShared() method because it is a shorthand for set($name, $definition, true);
• Remove attempt() method because it is a shorthand for has() + set()
• Rename setRaw() to setService() because getRaw() is actually getService() + $service->getDefinition()
• Remove getRaw() because it is getService() + $service->getDefinition()
• Modify setService($name, $raw_definition) to setService($raw_definition) because service name can be retrieved from the definition.

This results in

interface DiInterface
{
    public function set($name, $definiton, $shared = null);
    public function remove($name);
    public function get($name, $parameters = null);
    public function getShared($name, $parameters = null);
    public function getService($name);
    public function setService($raw_definition);
    public function has($name);
    public function wasFreshInstance();
    public function getServices();
    public static function setDefault($dependency_injector);
    public static function getDefault();
    public static function reset();
}
