Eliminate usage of ZF1 components

[vkublytskyi]

Usage of ZF1 components in Magento should be eliminated and replaced by (in preference order):

• embedded PHP libraries (e.g. Intl)
• ZF2/ZF3 component
• other well-supported stable PHP

During elimination of ZF1 components, backward compatibility changes are allowed but should be well motivated and provided with an explanation why this is necessary. If backward incompatible changes are made and removed ZF1 component was exposed in Magento interface/classes signatures, new code must wrap any usage of any 3rd party library (it is not allowed to expose usage of 3rd party libraries in Magento signatures)

Static Tests for eliminated components

To avoid regression issues with the introduction of new dependencies on the already cleaned usage of ZF1 components static tests should be implemented.
One of possible solution is reuse of dev/tests/static/testsuite/Magento/Test/Legacy/_files/restricted_classes.php. More accurate way would be to introduce special check that would understand Zend components structure (aka PSR-0 restricted namespaces)
