When we call `ServicesResetter::reset()`, we want to reset the

98b9be9b6a [Cache] fix using ProxyAdapter inside TagAwareAdapter
This is slimmed down version of: https://github.com/symfony/symfony/pull/28269 _(many of the fixes here are already part of 3.4)_
Adds:
- Test coverage for Predis with RedisCluster
- Removes usage of key versioning when on RedisCluster, besides performance aspect of that simplify / aligning clear() handling across cases
On any kind of multi loads, including tags loading, current code leads to
an explosion of Redis lookups slowing down performance.
This backports the code for mget() usage from 4.x in order to fix it.
It's done with one small improvment which would also be relevant for 4.x,
only using pipeline on cluster on predis as mget is more efficient.
