Bryan Boreham 31e8d8f79e Clarified rules and made SRC and DST consistent 
Matching up examples to rules to code was hard, so I added letters
(A), (B) etc.

This helped to track down various inconsistencies.  Now SRC and DST
NAT are symmetrical, and the code is quite similar, apart from
replacing the source vs destination of an adjacency.

Bryan Boreham 39721d8619 Fix up NAT mapper test 
- Add SRC and DST NAT flag in status.
- The port number was wrong from host1's perspective - it should see
  the mapped port on host2 not the real port inside the container.
- Add nodes at the other end of the connection, like the real probe does.
- Pass the local host name to MakeEndpointNodeID as it would be on the real probe.

Deal separately with SRC vs DST mapping.
Includes detailed rationale.

Bryan Boreham 85df164dc7 Stop special-casing the Docker bridge in Kubernetes mode 
In the case targeted, Kubernetes uses a bridge named 'cbr0'.

The 'docker0' bridge should be locally-scoped in most cases, and
exceptionally users can turn that off with --probe.docker.bridge=""

Daniel Holbach 905729af83 Start off FAQ document 
@fbarl and I talked about having a FAQ doc for Scope, where we can list
  tid-bits of information to work with Scope.

  Started off the doc with a piece that was discussed in #3406.

Bryan Boreham 94dbee2124 Move "hideous hack" for Kubernetes service network from probe to app 
This avoids side-effects from reporting Kubernetes from a
cluster-level probe, and removes a lie from the probe data.

Rather than do the work every time the probe sends a report, we do it
every time the app renders endpoints, which should be once per merged
report set.

Bryan Boreham f4dc368955 Don't buffer TIME_WAIT flows on conntrack start-up 
When the probe first starts we should only be interested in active
connections, and if the loop re-starts it's probably because too many
connections are opening and closing to keep up with, so it's good to
drop any that are already closed then too.

Refactor the code so `handleFlow` is only called on events, and handle
the initial list of connections directly.

Bryan Boreham c627802664 Refactor: remove some code that is now unnecessary 
- don't need another wrapper round `conntrack.Connections()`
- logPipe() was only for the command-line conntrack
