Poor code readability and need simplify class name

Hi team,
The autorest@beta is so good. But I think that the powershell code generated by autorest --powershell has poor readability.

For example: this is a line generated by autorest@beta
```
await ((Microsoft.Azure.Commands.Management.ProjectArcadia.Runtime.IEventListener)this).Signal(Microsoft.Azure.Commands.Management.ProjectArcadia.Runtime.Events.CmdletProcessRecordAsyncStart); if( ((Microsoft.Azure.Commands.Management.ProjectArcadia.Runtime.IEventListener)this).Token.IsCancellationRequested ) { return; }
```
I think it is two statements and can split into two lines.

Besides, my visual studio shows that `Microsoft.Azure.Commands.Management.ProjectArcadia.Runtime.IEventListener` can be simplified to `Runtime.IEventListener`.

Hope you can solve some problem about code readability.
