Before this commit, Hubble was ignoring proxy redirection information
from the policy-verdict events it received from the datapath. For
example, a cilium monitor event such as:
Policy verdict log: flow 0x0 local EP ID 1531, remote ID 35429, proto 17, egress, action redirect, match L3-L4, 10.240.0.62:37282 -> 10.240.0.63:53 udp
would be displayed in hubble observe as:
Sep 15 17:23:11.960: cilium-test/client-6488dcf5d4-f9kfl:37282 -> kube-system/coredns-d4866bcb7-zh5jv:53 L3-L4 FORWARDED (UDP)
This commit adds a new verdict REDIRECTED to signal such event. Such
events now appear as:
default/pod-to-external-fqdn-allow-google-cnp-5ff4986c89-n87h2:58314 -> kube-system/coredns-755cd654d4-j4vzh:53 UNKNOWN 5 (UDP)
A subsequent patch to the Hubble command line will display value 5 as
"REDIRECTED".

This is required to avoid `unknown Cilium policy verdict event` spans that happen due to addition of new REDIRECTED verdict (see cilium/cilium#17411). New version of Hubble hasn't been released yet, but the change has been backported to v0.8 branch (cilium/hubble#639).
