make pulling images faster by removing need for file removal

[rochdev]

Motivation

The current cleanup strategy takes ~1.5 minutes. We tried larger machines before which worked, but is more costly and made configuration more difficult. My hope is that the optimizations from the new action are enough for our use case.

Changes
