Scrape NPOL flow decision counters from VPP stats and export them with the
same pod and interface labels used for existing interface counters.
The exported metrics are:
cni_projectcalico_vpp_npol_rx_flows_allow
cni_projectcalico_vpp_npol_rx_flows_deny
cni_projectcalico_vpp_npol_tx_flows_allow
cni_projectcalico_vpp_npol_tx_flows_deny
Example output:
cni_projectcalico_vpp_npol_rx_flows_allow{
worker="0",
namespace="default",
podName="nginx",
podInterfaceName="eth0",
vppInterfaceName="tun3"
} 42
Also, document the new metrics and add Prometheus integration coverage that
verifies the counters are exposed after NPOL is configured on an interface.
