Remove duplicate logging code

**What this PR does / why we need it**:

Currently function `handleAttachPod` contains duplicate code which copies the AttachOptions output writer to the pod logging writer. This code can be refactored into a separate function. 

**Special notes for your reviewer**:

Refactor only, does not change program logic.

**Release note**:
```release-note
NONE
```
