Andrew Mason c3f4a998b2 [cmd/*] Switch to pflag for all CLI flag parsing (#10619) ... * Switch to `pflag` for all parsing This transparently swaps the cli parsing library used by `internal/flag` from the standard library `flag` package to `spf13/pflag`. It also introduces hook points for packages throughout the vitess codebase to register their flags for either all commands using `servenv` or a particular subset of commands. This allows these packages to continue to define their flag variables in a package-private way, but without polluting the global flagset.
