Use strongly typed errors to set HTTP status codes.
Error interfaces are defined in the api/errors package and errors
returned from controllers are checked against these interfaces.
Errors can be wraeped in a pkg/errors.Causer, as long as somewhere in the
line of causes one of the interfaces is implemented. The special error
interfaces take precedence over Causer, meaning if both Causer and one
of the new error interfaces are implemented, the Causer is not
traversed.

- They are configuration-only networks which
can be used to supply the configuration
when creating regular networks.
- They do not get allocated and do net get plumbed.
Drivers do not get to know about them.
- They can be removed, once no other network is
using them.
- When user creates a network specifying a
configuration network for the config, no
other network specific configuration field
is are accepted. User can only specify
network operator fields (attachable, internal,...)

This commit in conjunction with a libnetwork side commit,
cleans up the libnetwork SetClusterProvider logic interaction.
The previous code was inducing libnetwork to spawn several go
routines that were racing between each other during the agent
init and close.
A test got added to verify that back to back swarm init and leave
are properly processed and not raise crashes

- libnetwork controller Networks() already returns
a copy list. Also Networks() correctly skips any
network which ahs already been marked for deletion
while getNetworks implementation bypass this.

- When the node leaves the cluster, if any user run
container(s) is connected to the swarm network,
then daemon needs to detach the container(s) and
remove the network.

returned in "docker info". Currently info endpoint isnt using the
GetAllByCap, but relies on existing networks to get the plugin names.
This causes a basic issue when it comes to global network plugins which
swarm-mode relies on, wherein swarmkit will not be able to schedule the
network on the worker nodes due to the filtering logic.
In order to break this chicken & egg issue, we must start to use the
GetAllManagedPluginsByCap. We are unable to use GetAllByCap due to
various issues with Plugin-V1's lazy loading approach causing issues
especially during daemon restarts (which uses SystemInfo)

Change LOOKUP, ACQUIRE, and RELEASE to Lookup, Acquire, and Release.
This vendors a fork of libnetwork for now, to deal with a cyclic
dependency issue. The change will be upstream to libnetwork once this is
merged.

Currently the plugins pkg allows a single handler. This assumption
breaks down if there are mutiple listeners to a plugin of a certain
Manifest such as NetworkDriver or IpamDriver when swarm-mode is enabled.

When calling the /networks/ endpoint with a trailing
slash, the default network was returned.
This changes the endpoint to return the list of networks
instead (same response as `/networks` without trailing
slash).
Also updated the description for GetNetworkByName to
explain that the "default" network is returned if
no name or id is provided.

This PR adds support for running regular containers to be connected to
swarm mode multi-host network so that:
- containers connected to the same network across the cluster can
discover and connect to each other.
- Get access to services(and their associated loadbalancers)
connected to the same network

There are cases such as migrating from classic overlay network to the
swarm-mode networking (without kv-store), such a mechanism to allow
disconnecting a container even when a network isnt available will be
useful.

No user of GetNetworkDriverList needs to access the map by key.
The only user of GetNetworkDriverList is in docker info and with a map
the network list is always flipping because loop is not deterministic.
Fix this by returning a string slice which instead is.

As described in our ROADMAP.md, introduce new Swarm management API

This PR is fully backward compatible (joining a Swarm is an optional
feature of the Engine, and existing commands are not impacted).
