Dependency on Magento was sneaked in as part of the Computed Resolver work

[pawel-siejba]

This package has no declared composer dependencies on Magento, yet in 6d25b49 a dependency is hardcoded.

This means that it cannot be considered anymore as a standalone implementation of upward in PHP.

Following Dependency Inversion principle we should create an interface which \Magento\UpwardConnector\Model\ComputedPool implements, or make \Magento\UpwardConnector\Model\ComputedPool part of the magento/upward-php together with \Magento\UpwardConnector\Api\ComputedInterface.
