Adds the ability for mockPromMetrics in the job-componentsTestContext to properly gather metrics by labels. This was necessary to test count_by_field in standard-assets.
Add clusterManagerType to JobHarnessOptions used by the base-test-harness. This will set context.sysconfig.teraslice.cluster_manager_type, which must be kubernetes for prom metrics to be enabled.
