No warning when login needs to be run

### **This is autogenerated. Please review and update as needed.**

## Describe the bug
az ssh vm command failed with a massive error message (took up my entire terminal window). When I ran az login again though, the command worked fine again. When I'm overdue to login again, the ssh vm command should just say that simply.

**Command Name**
`az ssh vm
Extension Name: ssh. Version: 0.1.5.`

**Errors:**
```
Please run 'az login' to setup account.

```
