Expand functionality: limit group for adapter

[killondark]

Hey, @Envek. In continue my PR. I want to extend the metrics limit functionality for the adapter.

# current version:
Yabeda.configure do
  group :mushrooms do
    adapter :basket_adapter
    counter :champignon_counter
  end
end

# added version:
Yabeda.configure do
  group :mushrooms do
    counter :champignon_counter
  end

  adapter :basket_adapter do
    include_group :mushrooms
  end
end

But specs do randomly green or red. For example:

1) Yabeda::Counter when config has no group execute perform_counter_increment!
   Failure/Error: let(:counter) { Yabeda.test_counter }
   
   NoMethodError:
     undefined method `test_counter' for Yabeda:Module
   # ./spec/yabeda/counter_spec.rb:14:in `block (3 levels) in <top (required)>'
   # ./spec/yabeda/counter_spec.rb:4:in `block (2 levels) in <top (required)>'
   # ./spec/yabeda/counter_spec.rb:30:in `block (3 levels) in <top (required)>'

What do you think about this? Thanks.

Hi, @Envek. I done actualize and fixed failing specs. Running specs randomly is was a problem.

Thanks for the pull request and sorry for the late reply. I will try to get to this in a few days.

It is not good when test suite result depends on order in which tests are executed. These dependencies need to be detected and removed (maybe something need to be added to the Yabeda.reset!)

I agree, it just solved my problem. Reverted it.
