PapiExecutor always verifies
Do not support returning unverified replies anymore. Basically, ".get_replies().verify_replies()" is now just ".get_replies()". This allows fairly large simplifications both at call sites and in PapiExecutor.py + Rename get_dumps to get_details. + Introduce get_reply and get_sw_if_index. + Rename variables holding get_*() value, + e.g. get_stats() value is stored to variable named "stats". + Rename "item" of subsequent loop to hint the type instead. + Rename "details" function argument to "verbose". + Process reply details in place, instead of building new list. - Except hybrid blocks which can return both list or single item. - Except human readable text building blocks. + Rename most similar names to sw_if_index. - Except "vpp_sw_index" and some function names. + Use single run_cli_cmd from PapiExecutor. + Do not chain methods over multiple lines. + Small space gain is not worth readability loss. + Include minor code and docstrings improvement. + Add some TODOs.
