Initial changes

These are incomplete, but provide the basic skeleton of change.

Accepts a config file, or environment variables for authentication to
one or more RedFish endpoints. The config file can specify global
credentials, as well as per-host credentials.

Adds a `--json` flag for printing the output as JSON.

Adds a `--insecure` flag for connecting to untrusted RedFish endpoints.

Allows hosts to be provided as positional arguments, or by piping

```
echo host1 host2 | gru show system

gru show system host1 host2
```
