High memory usage (server-side)
Describe the bug I've deployed LabelStudio in a docker container and after some usage, the container RAM usage just keeps growing. It's sitting at 1.7GiB right now.

To Reproduce Steps to reproduce the behavior:
- Deploy on Docker
- Do some annotations
- See the RAM usage growing
Environment (please complete the following information):
- Label Studio Version: 1.5.0.post0
Memory Utilization within CloudWatch is based on real memory + swap space + probably RSS. So it's not true.
You can ssh on this VM and run top or htop(recommended, install it using apt-get)
Right now, htop shows RES=842M. I'll edit this message in a few hours if I see the RAM usage increasing too much, thanks !
34min later: RES=1231M
1h10 later: RES=1410M
~3h later: RES=1623M
