rc: add option to skip running check for list method
Running check may be slow and increase result time in the other of 70ms
for the list method.
Add an option to skip running check by passing the skip_running_check as
true in the list method args to speedup execution if the running info is
not needed.
With the option set to true the execution time lower to just 5ms.
