High memory consumption and memory leak (still an issue)

Opening a new issue because the problem described here https://github.com/aws/aws-codedeploy-agent/issues/32 still exists.

Basically, when codedeploy finishes, the agent doesn't release the memory back to the OS and the workaround is to restart the agent.

I've enabled verbose logging. Briefly looking at the logs, seems that unzip utility is used to unarchive the bundle:
```
$ cat codedeploy-agent.log | grep "LinuxUtil"

Where can I securely share the 127MB `codedeploy-agent.log` file (generated from a single deployment)? I don't want to share it publicly.

My environment:
EC2 instance running Ubuntu 20
ruby 2.7.0p0 (2019-12-25 revision 647ee6f091) [aarch64-linux-gnu]
