feat: add methods for listing config profiles

New method:

```javascript
Promise<Array<{ name, description }>> ipfs.config.profiles.list()
```

BREAKING CHANGE:

```javascript
Promise<{oldCfg, newCfg}> ipfs.config.profile(name, opts)

// is now
Promise<{old, new}> ipfs.config.profiles.apply(name, opts)
```

Possibly contentious;

Adds `callbackify` as a dependency, see ipfs/js-ipfs#2506
for discussion.
