niksis02 6c564febb9 feat: makes root creds usable for admin subcommand with lower precendence ...

Closes #1760

The admin subcommand accepts the `--access` and `--secret` flags as admin user credentials. This change makes these flags optional and allows the root user credentials to be used as admin credentials with lower precedence when the admin flags are omitted.

Both invocation styles are now valid:

```bash
versitygw admin --access user --secret pass -er http://127.0.0.1:7070 list-buckets
```

and

```bash
versitygw --access user --secret pass admin -er http://127.0.0.1:7070 list-buckets
```

Additionally, if `ROOT_ACCESS_KEY` and `ROOT_SECRET_KEY` are already set, the following also works:

```bash
versitygw admin -er http://127.0.0.1:7070 list-buckets
```
