feat: Add configurable device plugin resource name for node management port

Add nodeMgmtPortDpResourceName to the Helm chart to allow specifying a
device plugin resource for the ovnkube-node management port container.
When set, the resource is included in container requests/limits and
exposed via the OVNKUBE_NODE_MGMT_PORT_DP_RESOURCE_NAME environment
variable.
