Add **kwargs to dynamic redis client method definition

[IvanTakarlikov-st]

This will allow to avoid Ruby deprecation warnings on Ruby 2.7

gems/sidekiq-7.2.2/lib/sidekiq/redis_client_adapter.rb:36: warning: Using the last argument as keyword parameters is deprecated; maybe ** should be added to the call
gems/redis-client-0.21.1/lib/redis_client.rb:275: warning: The called method `call' is defined here

Testing env:

Warning[:deprecated] = true
def call(*command, **kwargs)
  puts command, kwargs
end

def wcall(*args); call(*args);end

def wcall2(*args, **kwargs); call(*args, **kwargs);end

Testing:

irb(main):019:0> wcall(1,2,3, foo: 'bar')
(irb):15: warning: Using the last argument as keyword parameters is deprecated; maybe ** should be added to the call
(irb):12: warning: The called method `call' is defined here

{:foo=>"bar"}
=> nil
irb(main):020:0> wcall2(1,2,3, foo: 'bar')

{:foo=>"bar"}

Thanks for showing me that redis-client does support keyword args! Happy to see it.
