[BUG]: Metadata cache reset flushes whole redis

[hostaway-greg]

Describe the bug
When you use metadata cache with redis adapter, and you call $cache->reset() it sends flushdb to redis server. This clears whole redis database, which can cause a lot of issues.

Expected behavior
Either clear only set keys (store keys internally in Redis adapter) or maybe use prefix mechanism?

Also, documentation should reflect this.

I did not check other adapters.

Details

• Phalcon version: 5.6.2
• PHP Version: 8.5.2
• Operating System: Linux
• Installation type: compiled from source
• Server: nginx + fpm

Additional context

There is some work that I did for v6 that will simplify and help the storage classes. I need to align it with v5 and also fix the clear method. The prefixed keys are not handled the same in all classes so I need to write some more tests to ensure that clear deletes what it is supposed to.
