Current memory limit causes OOM

[jhead-slg]

What steps did you take and what happened:
With larger clusters (100+) machines and a lot of machine deployments happening the container uses up to ~35Mi of memory. It was getting OOM killed until I modified the limit to be 50Mi instead of the current 30Mi.

What did you expect to happen:
The pod should not OOM.

Anything else you would like to add:
N/A

Environment:

• cluster-api-provider-packet version: v0.3.9
• Kubernetes version: (use kubectl version):
• OS (e.g. from /etc/os-release):
