feat: new Methods

[EhsanFox]

What this PR is about: Adding some new methods for easier and better access and management

What has been changed:

• Created removeItem method in FS-Storage, Memory-Storage, CacheContainer, and Storage types
• Created getAll method that would return all saved Data in FS-Storage, Memory-Storage, CacheContainer, and Storage types
• Added an option to return the saved data before removing it on CacheContainer Class
• Instead of setting a key value to null which still takes storage, we remove them with removeItem method

What needs to be changed: unfortunately, I don't have any experience with Redis, so I left storage-elasticsearch and storage-ioredis unchanged, I hope you can fix or find a solution for them.

Possible solutions: We can remove the removeItem & getAll methods from CacheContainer, however, users can still access those methods from storage directly and we can implant generic typings of methods in the IStorage interface instead.
