[#927] neofs-adm: provide better error message if endpoint is missing

Browse source 
Note that we cannot mark `--rpc-endpoint` flag as required because
it can be taken from config.

Before:
```
Error: can't create N3 client: failed to get network magic: Post "": unsupported protocol scheme ""
```

Now:
```
Error: can't create N3 client: missing endpoint
```
