ZF2-137: CLONE - Tags should be emulated when they are not supported

Description

Actually the documentation notes TAGS as best variant to be used for cleaning cache entries. This is only the case for 2 or 3 of the supported backends.

All backends which do not support tags should emulate tags within Zend_Cache when possible.

Comments

cloned from ZF-6400

For ZF2 it should be possible to implement a plug-in to add tagging functionality.
