filling up logs in case of issues

Usually a diagnostic session wants to check the local state
without this flag the network is joined and left every iteration
altering actually the daemon status.
Also if the diagnostic client is used against a live node, the
network leave has a very bad side effect of kicking the node
out of the network killing its internal status.
For the above reason introducing the flag -a to be explicit
so that the current state is always preserved

Previously, support script dumped the host iptables filter/nat tables,
and each overlay network's network inspect and 'bridge fdb show' and
'brctl showmacs'. Now we collect much more information. Support script
dumps iptables filter/nat/mangle, routes and interfaces from iproute2,
bridge fdb table, & ipvsadm table, for the host and containers/overlay
networks on the host. We also dump a redacted copy of the container
health check status and other debugging information for each container,
in JSON format, and 'docker network inspect -v' for each overlay, if the
client/server support the -v flag.

Setting ndots to 0 does not allow to resolve search domains
The default will remain ndots:0 that will directly resolve
services, but if the user specify a different ndots value
just propagate it into the container

- the client allows to talk to the diagnostic server and
decode the internal values of the overlay and service discovery
- the tool also allows to remediate in case of orphans entries
- added README

Avoid waiting for a double notification once a node rejoin, just
put it back to active state. Waiting for a further message does not
really add anything to the safety of the operation, the source of truth
for the node status resided inside memberlist.

This PR contains a fix for moby/moby#30321. There was a moby/moby#31142
PR intending to fix the issue by adding a delay between disabling the
service in the cluster and the shutdown of the tasks. However
disabling the service was not deleting the service info in the cluster.
Added a fix to delete service info from cluster and verified using siege
to ensure there is zero downtime on rolling update of a service.

If the gcthresh denies the insertion the peerAdd will fail.

In sandbox creation we disable IPV6 config. But this causes problem in live-restore case
where all IPV6 configs are wiped out on running container. Hence extra check has been added
take care of this issue.

VETH interface was not cleaned up when DockerD got killed between addEndpoint and updateToStore calls.
I have added logs and made sure calling updateToStore before addEndpoint contains same values.
Hence moving up the call looks safer and VETH gets cleaned up even after DockerD gets killed in the middle.
