Mike BryantandAlfonso Acosta 764afb6301 Add options to hide args and env vars (#2306) 
* Add options to hide args and env vars

To allow for use of weave-scope in an unauthenticated environment,
add options to the probe to hide comand line arguments and
environment variables, which might contain secret data.

Fixes #2222

* Change docker.NewRegistry arguments to be a struct

* Remove redundant declarations of default values

* Move registry options outside to improve readability

Mike Lang a49f1c9559 ECS service controls: Don't allow scale down below 1 
as currently this would make it disappear (#2085).

Mike Lang fad3e88269 Rename ECS Service node ids to be cluster;serviceName 
This is important for two reasons:
* It prevents nasty false-equality bugs when two different services from different ECS clusters
  are present in the same report
* It allows us to retrieve the cluster and service name - all the info we need to look up the service -
  using only the node ID. This matters, for example, when trying to handle a control request.

Alban Crequy f1e2b5d93a probe: conntrack: fix output parsing 
With net.netfilter.nf_conntrack_acct = 1, conntrack adds the following
fields in the output: packets=3 bytes=164

And with SELinux (e.g. Fedora), conntrack adds: secctx=...

The parsing with fmt.Sscanf introduced in #2095 was unfortunately
rejecting lines with those fields. This patch fixes that by adding more
complicated parsing in decodeFlowKeyValues() with FieldsFunc and SplitN.

Fixes #2117
Regression from #2095

Alfonso Acosta 89a0ab6799 Fix test data and improve /proc/net/tcp header parsing 
The header checking code was unsafe because:

1. It was accessing the byteslice at [2] without ensuring a length >= 3
2. It was assuming that the indentation of the 'sl' header is always 2 (which seems to be the case in recent kernels https://github.com/torvalds/linux/blob/8f18e4d03ed8fa5e4a300c94550533bd8ce4ff9a/net/ipv4/tcp_ipv4.c#L2304 and https://github.com/torvalds/linux/blob/8f18e4d03ed8fa5e4a300c94550533bd8ce4ff9a/net/ipv6/tcp_ipv6.c#L1831 ) but it's more robust to simply trim the byteslice.

Mike Lang 1d63830792 awsecs reporter: Add lots of debug logging and fix bugs 
- describeServices wasn't describing the partial page left over at the end,
  which would cause incorrect results
- the shim between listServices and describeServices was closing the channel every iteration,
  which would cause panic for write to closed channel
- client was not being saved when created, so it gets recreated each time
- we were describeTasks'ing even if we had no tasks to describe
