Add resource limits to the long running containers (#117)

Prevents accidental resource exhaustion

Signed-off-by: Steve Wills <[email protected]>

## Description

While looking at the issue in #115 I decided to add resource limits to avoid future accidental resource exhaustion. Not strictly required and perhaps the limits themselves can use tweaking, but it seems useful to add a safety.

## Why is this needed

See description

Fixes: #

## How Has This Been Tested?
In VM

## How are existing users impacted? What migration steps/scripts do we need?

Avoids potential issue

## Checklist:

I have:

- [N/A] updated the documentation and/or roadmap (if required)
- [N/A] added unit or e2e tests
- [N/A] provided instructions on how to upgrade
