satellie/gc: enable garbage collection on the satellite

[littleskunk]

What: Enable garbage collection on the satellite side. Don't enable it on the storage node.

Why: Garbage collection is working great on the satellite side. We don't see any performance impact. We can go ahead and enable it on all satellites. On the storage node side we can't because there is an annoying timeout issue.

Please describe the tests:

• Test 1:
• Test 2:

Please describe the performance impact:
