Convert lastSuccessfullUploadTime into a GaugeVec with one dimension: bucket, which makes client_golang *not* make that metric unless at least one value has appeared. This is better for users since Grafana will show that last upload has been 49+ years ago instead of N/A when no uploads had happened before. Fixes thanos-io#886.
