rework of auth cmd planned in CM-22207

@MichalBor I start thinking about the move --output option to global space. It should be cycode --output json for example. Otherwise, the option position will be dynamic and depend on the command space. There is cycode scan --output. And in this PR cycode auth --output. What do you think?

@MarshalX sounds good

@MichalBor the option was moved to the global space. I saved backward comparability with scan --output option too. The cyclient was refactored and all error handling happens in the base class. Also, I migrated a few direct calls of "requests" to calls of our cyclient

@MichalBor I am proud to say that refactored things here were covered by unit tests in #103. Including cyclient with error handling and --output option. Let's review and merge tests first to be able to test this PR
