Change to accept a third-party strategy

[slywalker]

If open the strategy, my dream will be spread.

$this->addBehavior('CakeDC/Enum.Enum', [
    'classMap' => [
        'third_party' => 'OtherPlugin\Model\Behavior\Strategy\ThirdPartyStrategy'
    ],
    'lists' => [
        'article_category' => [
            'strategy' => 'third_party'
        ],
    ]
]);

Coverage increased (+0.2%) to 88.158% when pulling 6fa60b6 on slywalker:feature-third-party-strategy into a9387bf on CakeDC:master.
