HOTFIX - Bumps memory of celery task in perf

[coreycarvalho]

Description

Celery task on Friday OOM'd, so we are going to bump this task from 4GB of memory to 5GB. I'm opting for a smaller jump because the average memory remained at around 50% utilization, but maximum jumped up and killed the task. If we need more we can always add more.

How Has This Been Tested?

Config change, nothing to test.
