Summary:
This PR enhances the C2D Docker engine to allow customization of CPU and RAM resource limits (total, max, min) via the envConfig.resources configuration. It initializes default resource values based on system information (sysinfo) and then applies any specified overrides from the environment configuration, improving flexibility in resource allocation for compute jobs.

Comments:
• [INFO][other] The PR correctly applies custom total, max, and min values for CPU and RAM. It might be beneficial to consider adding explicit validation (e.g., min <= max <= total) here or ensure it's handled upstream when envConfig.resources is parsed, to prevent scenarios where custom values could lead to invalid resource configurations. This would enhance the robustness of the resource setup.
• [INFO][style] The current approach of creating cpuResources and ramResources objects first and then updating them based on envConfig is clear and functional. The if (res.total) checks are good for robustness against partial envConfig entries. If envConfig.resources entries for CPU/RAM are always expected to provide all three (total, max, min) when present, a slightly more concise assignment without the if checks could be used, but the current approach is safer.
