Retracted: 1.2.2 was released on main branch with a breaking change that was not
intended to be released in 1.2.x:
https://github.com/Kong/gateway-operator/commit/3876430e09e61edce58bd8464989e33236bd1872
This retraction is to prevent it from being used and from breaking builds of dependent projects.
FlagSet returns bare underlying flagset of the cli. It can be used to register
additional flags. They will be parsed by Parse() method. Caller needs to take
care of values set by flags added to this flagset.
Parse parses flag definitions from the argument list, which should not include the command name.
Must be called after all additional flags in the FlagSet() are defined and before flags are accessed
by the program. It returns config for controller manager.
