This PR implements [probabilistic early expiration](https://en.wikipedia.org/wiki/Cache_stampede#Probabilistic_early_expiration) on top of `$cache->get($key, $callback);`
It adds a 3rd arg to `CacheInterface::get`:
> float $beta A float that controls the likelyness of triggering early expiration. 0 disables it, INF forces immediate expiration. The default is implementation dependend but should typically be 1.0, which should provide optimal stampede protection.

This is additional work toward making more cache implementations use the `PruneableInterface` contract. Specifically, this pull request focuses on `(Pdo|Chain)(Cache|Adapter)`, as suggested by @nicolas-grekas in https://github.com/symfony/symfony/pull/23451#issuecomment-316735763.

- added `Symfony\Component\Cache\PruneableInterface` so PSR-6 or PSR-16 cache implementations can declare support
for manual stale cache pruning
- added FilesystemTrait::prune() and PhpFilesTrait::prune() implementations
- now FilesystemAdapter, PhpFilesAdapter, FilesystemCache, and PhpFilesCache implement PruneableInterface and
supports manual stale cache pruning
- Added `cache:pool:prune` command via `Symfony\Bundle\FrameworkBundle\Command\CachePoolPruneCommand` to allow
manual stale cache item pruning of supported PSR-6 and PSR-16 cache pool implementations
- Added `Symfony\Bundle\FrameworkBundle\DependencyInjection\Compiler\CachePoolPrunerPass` compiler pass to fetch
all cache pools implementing `PruneableInterface` and pass them to the command as an `IteratorArgument` so
these references are lazy loaded by the command
- updated changelogs as appropriate
