grafana#469 changed the default allValue for addMultiTemplate from `null` to `'.+'`. I want to make it configurable. Reason: we use addMultiTemplate to add a namespace dropdown in the tempo-mixin: https://github.com/grafana/tempo/blob/a1a95b35e15741061fc7119256aaeab78083dfbc/operations/tempo-mixin/dashboard-utils.libsonnet#L28 https://github.com/grafana/tempo/blob/a1a95b35e15741061fc7119256aaeab78083dfbc/operations/tempo-mixin/yamls/tempo-resources.json#L1873-L1900 This dropdown is populated with the namespaces a Tempo cluster is running in. The current behaviour (with `allValue: '.+'`) is confusing, because selecting All in the dropdown ends up querying all namespaces. The previous behaviour (with `allValue: null`) only queries the namespaces that are returned by the query. The reason we got confused is that in our dashboard you can select a cluster and if you know there is only 1 Tempo namespace in that cluster you kind of expect to only see data from that namespace. But with `allValue: '.+'` you get data from all namespaces in that cluster. So we're mistakenly looking at queriers from a non-Tempo cluster and wondering why CPU was so high.
