Description

When the on-disk and provided master_addresses don't match, the error message is misleading as it shows as they're swapped.

e.g. in case master_addresses lists 3 masters, but on-disk has only one, it looks like this:

$ kudu-master --master_addresses=master1,master2,master3
F0724 14:09:13.123456 53353 master_main.cc:77] Check failed: _s.ok() Bad status: Invalid argument: Unable to initialize catalog manager: Failed to initialize sys tables async: on-disk master list (master1:7051, master2:7051, master3:7051) and provided master list (master1:7051) differ. Their symmetric difference is: master2:7051, master3:7051
