Improve performance of capture_ems_targets

For Kubernetes type providers if the ems has metrics credentials then
all instances of container_nodes, container_groups, etc... supports
capture.

We don't have to check `.supporting(:capture)` if we are in a kubernetes
provider, but this isn't generally true so only implement this behavior
in k8s.
