Unsuccessful (because not existing) cordova commands

I looked a bit at the Cordova Telemetry data about the commands executed:
https://datastudio.google.com/reporting/0B-Ja5cNOX_XLTElHdWd4V2NUem8/page/zkJF

Looking at the `unsuccessful` commands, you quickly notice that quite a few are common misunderstandings (or just mistypes of) what Cordova commands exist:

(standard current data set, filtered to >100 usages)

When the user uses one of those commands they already get a helpful note to use the help command:

```
λ cordova install
Cordova does not know install; try `cordova help` for a list of all the available commands.
```

But I think we could do better.

For all the subcommands that are missing `platform` or `plugin`, we could just tell them that e.g. "`add` is only a valid subcommand of `cordova platform` or `cordova plugin`" (or similar, same for `remove` and `rm` etc.).

`ios` and `android` are only valid parametrs for subcommands of `platform` like `cordova platform add`, `cordova platform run` etc.

Common typos we could just accept and redirect to the correct command: `platfrom`, `plataform`, `plaform`, `plateform`, `paltform`, `requirement` etc.

Mixups between CLIs as well: `start` should probably be `create` (and is because Ionic CLI calls their "create new project" command `start`)

Is there any reason why we should _not_ do this and improve the live of our users?
