Moving verification of input to the earliest place is the best way to decrease the need to validate this further downstream.
Additionally, some of the existing checks were.... lacking :)

0.22.0 changed allowed values for app names, making it more difficult for users to fix their app names - you need to either downgrade+rename or recreate the app. The `apps:rename` command can now rename these old applications to the new standard.
Also drop some app name verification from internal commands. Duplicate verification doesn't help much, and though it isn't excessively slow, it does prevent us from running commands against old apps that exist.
Refs #4267
When setting the `--app` flag, there was a special case for the config plugin. This plugin used to take the `--no-restart` flag as the first argument - and still did until this change - resulting in an invalid call to the plugin subcommands. What is worse is that this functionality carried over to all other plugins as they were rewritten in golang, and thus the issue spread without us knowing.
The fix is to support GNU flag parsing rules, which Golang does not do by default (Because Of Reasons™). Switching to `github.com/spf13/pflag` fixes this issue, and also allows positional arguments to be placed wherever, even in the middle of flags.
Closes#4255
