Allow to configure resources for shutdown manager

[Hartigan]

Description:
Currently, envoy proxies pods have sidecar with only requests configured in resources. This behavior doesn't allow to setup envoy proxies pods with QoS Guaranteed. QoS Guaranteed is required for some features like Control CPU Management or NUMA-aware memory manager

Simple solution: add limits which equals requests for this sidecar. Or allow to setup requests and limits via custom k8s resources
