* Move common rule parsing logic to a common package that
  also can be imported out of `frostfs-node`;
* Move common flags and commands to `cmd/internal/common/ape` package to
  avoid duplication. Since `frostfs-adm` and `frostfs-cli` subcommands
  are able to use commands, thee same flag names and their descriptions.
