[12.x] Simplify driver instance decoration in manager

[daniser]

Simple stub method has been added to manager in order to simplify driver instance decoration.
It can be useful if you want to decorate all your drivers at once with, for example, caching layer or similar.

Current alternatives are:

• Decorate drivers separately in their own create{...}Driver methods (see CacheManager);
• Override driver or createDriver method in your manager (too much boilerplate code);
• Decorate in service provider with extend (downside that it'll decorate only default driver).

I'm closing this because overriding createDriver while calling parent method is pretty much the same😄
