add kubernetes-pod builtin pattern for pod names (#164)

Browse source 
The existing "kubernetes" pattern matches resource type paths
(e.g. deployment.apps/my-app) but not pod names, which are
the most commonly copied k8s identifiers for kubectl logs,
describe, exec, etc.

Pod names like "nginx-deployment-66b6c48dd5-7xb2r" have a
distinctive structure: <name>-<replicaset-hash>-<pod-hash>.
The regex uses the actual k8s hash alphabet (consonants +
digits 2,4-9, no vowels) from apimachinery/pkg/util/rand,
which avoids false positives on normal terminal text.
