Volcano support SidecarContainer

[Monokaix]

What would you like to be added:

Add sidecarContainer support for volcano scheduler, which needs volcano scheduler re-compute pod resource requests.

Why is this needed:

SideCarContainer is a beta feature and is enabled by default in k8s v1.29, volcano has not yet adapt the feature, this may cause the scheduler to undercalculate the resources for the pod, and then the kubelet admit failed after the pod is scheduled to the node, because the sidecarcontainer is a new kind of initcontainer, so the pod initialization request resources need to be recalculated.

Refer to:

1. https://github.com/kubernetes/enhancements/tree/master/keps/sig-node/753-sidecar-containers#resources-calculation-for-scheduling-and-pod-admission
2. Add SidecarContainers feature kubernetes/kubernetes#116429
