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.

This function was implemented in dd4950f36d
which added a "key" field, but that field was never used anywhere, and
still appears unused.

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 `#`).

After moving libnetwork to this repo, we need to update all the import
paths for libnetwork to point to docker/docker/libnetwork instead of
docker/libnetwork.
This change implements that.
