Julius VolzandTom Wilkie 4fa40e22b2 Rework Scope metrics according to Prometheus conventions. (#1615) 
* Rework Scope metrics according to Prometheus conventions.

- counters should end with _total
- elaborated and added units to help strings
- recommended for cache hit/miss metrics: track only the total and the
  hits and in separate metrics, since the most common query will be
  "hits / total"
- track all times in seconds (base units), which has become the standard
  recommendation
- other small changes

There could be more changes that would require more thinking (what
dimensions to use, summaries vs. histograms, etc.), but this is probably
enough controversial material already :)

* Use timeRequestStatus() in sqs_control_router.go.

Tom Wilkie 277bd70491 Don't every store NEW conntrack flows (only every store updates). (#1541) 
This closes a small window where we might produce reports which contain flows that are NEW but have never seen an UPDATE, which can potentially be invalid.

Alban CrequyandTom Wilkie 42ad3aa12b Scope slow: improve error messages for debugging (#1534) 
* alpine: dl-4.alpinelinux.org is dead, use another server

* increase buffer for docker stats

Attempt to avoid the following message:
docker container: dropping stats.

* probe: better timeout error messages

The logs contains the following messages:

Process reporter took longer than 1s
K8s reporter took longer than 1s
Docker reporter took longer than 1s
Endpoint reporter took longer than 1s

This patch prints how long it takes.
