Subject: [PATCH] cmd: Add ability to list all profiles (#29)

Creates a `list` command which will allow you to list all configured
profiles. At the moment, the output is only profile name, auth mechanism
and the email associated (for API keys). This can be extended in the
future as more information is needed.

Example output

```
PROFILE NAME    	AUTHENTICATION TYPE	EMAIL
test-api-key    	api_key            	jacob@example.com
test-api-token  	api_token
```

Closes #8
