No way to create custom key generator for storage

[VladStepanov]

Is there an existing issue that is already proposing this?

• I have searched the existing issues

Is your feature request related to a problem? Please describe it

I just want to have a opportunity to generate my own key. Md5 hash is good, but in real life there may be situations then you should connect to your redis and check keys rl-*.
I can't believe that such a popular lib doesn't have such a simple thing.

Describe the solution you'd like

Global default customKey function

.forRoot({
  customKey (context) {}
})

Local customKey function

class ThrottlerFoo extends ThrottlerGuard {
  customKey (context) {}
}

Local function overrides global

Teachability, documentation, adoption, migration strategy

No response

What is the motivation / use case for changing the behavior?

In real life there may be situations then you should connect to your redis and check/drop constraints

You can extend the ThrottlerGuard and override the generateKey method

I think this should be highlighted in the documentation.
