Using resource labels is mandatory for most Stackdriver resources other then
Global, i.e.k8s_pod.While setting resource type is supported in
StackdriverProperties, it is not possible to set labels in the same, configurable way.Configuring resource type only lead to issues as described in micrometer-metrics/micrometer#1907.
Using valid resource type along with required labels makes it possible to use given metric in a wider set of
GCP solutions, i.e. custom metric based GKE horizontal pod autoscaler.
