Luke Granger-Brown 82db8f7f1e gerrit01: some more tuning 
* flip off proxy_buffering again
* enable REVWALK_USE_PRIORITY_QUEUE
* enable delta compression, because that's not a bottleneck and it's
  nicer on bandwidth

emily 8d2a367e92 grafana-agent: make bagel.monitoring.grafana-agent.exporters an attrset 
This allows us to use multiple jobs, one for each additional exporter,
and set their `job_name` accordingly.

`job_name` is exported as `job` label on the resulting metrics.
This allows us to quickly get an understanding what metrics of an
exporter are actually available by simply filtering all metrics by
`{job="$jobname"}`

emily db8c831c2f grafana-agent: set hostname label on all metrics 
This is handy to quickly see all metrics exported by a node, without
having to mangle with the already existing `instance` label.

`hostname` is essentially a variant of `instance` but without ports.
