This command was originally added by ea7f555446
to test the code snippet put into libnet's README.md. Nothing compiles
this file and it doesn't add any value to the project. So better remove
it than maintaining it.
This commit also removes the code snippet from libnet's README.md for
the same reasons.

We don't need C-style callback functions which accept a void* context
parameter: Go has closures. Drop the unnecessary httpHandlerCustom type
and refactor the diagnostic server handler functions into closures which
capture whatever context they need implicitly.
If the node leaves and rejoins a swarm, the cluster agent and its
associated NetworkDB are discarded and replaced with new instances. Upon
rejoin, the agent registers its NetworkDB instance with the diagnostic
server. These handlers would all conflict with the handlers registered
by the previous NetworkDB instance. Attempting to register a second
handler on a http.ServeMux with the same pattern will panic, which the
diagnostic server would historically deal with by ignoring the duplicate
handler registration. Consequently, the first NetworkDB instance to be
registered would "stick" to the diagnostic server for the lifetime of
the process, even after it is replaced with another instance. Improve
duplicate-handler registration such that the most recently-registered
handler for a pattern is used for all subsequent requests.

The github.com/containerd/containerd/log package was moved to a separate
module, which will also be used by upcoming (patch) releases of containerd.
This patch moves our own uses of the package to use the new module.

Now that most uses of reexec have been replaced with non-reexec
solutions, most of the reexec.Init() calls peppered throughout the test
suites are unnecessary. Furthermore, most of the reexec.Init() calls in
test code neglects to check the return value to determine whether to
exit, which would result in the reexec'ed subprocesses proceeding to run
the tests, which would reexec another subprocess which would proceed to
run the tests, recursively. (That would explain why every reexec
callback used to unconditionally call os.Exit() instead of returning...)
Remove unneeded reexec.Init() calls from test and example code which no
longer needs it, and fix the reexec.Init() calls which are not inert to
exit after a reexec callback is invoked.

This command was useful when overlay networks based on external KV store
was developed but is unused nowadays.
As the last reference to OverlayBindInterface and OverlayNeighborIP
netlabels are in the ovrouter cmd, they're removed too.

Per the Interface Segregation Principle, network drivers should not have
to depend on GetPluginGetter methods they do not use. The remote network
driver is the only one which needs a PluginGetter, and it is already
special-cased in Controller so there is no sense warping the interfaces
to achieve a foolish consistency. Replace all other network drivers' Init
functions with Register functions which take a driverapi.Registerer
argument instead of a driverapi.DriverCallback. Add back in Init wrapper
functions for only the drivers which Swarmkit references so that
Swarmkit can continue to build.
Refactor the libnetwork Controller to use the new drvregistry.Networks
and drvregistry.IPAMs driver registries in place of the legacy ones.

The correct formatting for machine-readable comments is;
//<some alphanumeric identifier>:<options>[,<option>...][ // comment]
Which basically means:
- MUST NOT have a space before `<identifier>` (e.g. `nolint`)
- Identified MUST be alphanumeric
- MUST be followed by a colon
- MUST be followed by at least one `<option>`
- Optionally additional `<options>` (comma-separated)
- Optionally followed by a comment
Any other format will not be considered a machine-readable comment by `gofmt`,
and thus formatted as a regular comment. Note that this also means that a
`//nolint` (without anything after it) is considered invalid, same for `//#nosec`
(starts with a `#`).

The BurntSushi project is no longer maintained, and the container ecosystem

Since Go 1.7, context is a standard package. Since about Go 1.9 time,
all x/net/context provides is a few aliases to types in context, meaning
"x/net/context" and "context" can be mixed freely.
Some vendored packages still use x/net/context, so vendor entry remains
for now.

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

This patch updates all dependencies to match what is
used in moby/moby. Making the dependencies match
what is used in that repository makes sure we test
with the same version as libnetwork is later built
with in moby.
This also gets rid of some temporary forks that were
needed during the migration of Sirupsen/logrus to
sirupsen/logrus.
