When requesting information about the daemon's configuration through the `/info`
endpoint, missing features (or non-recommended settings) may have to be presented
to the user.
Detecting these situations, and printing warnings currently is handled by the
cli, which results in some complications:
- duplicated effort: each client has to re-implement detection and warnings.
- it's not possible to generate warnings for reasons outside of the information
returned in the `/info` response.
- cli-side detection has to be updated for new conditions. This means that an
older cli connecting to a new daemon may not print all warnings (due to
it not detecting the new conditions)
- some warnings (in particular, warnings about storage-drivers) depend on
driver-status (`DriverStatus`) information. The format of the information
returned in this field is not part of the API specification and can change
over time, resulting in cli-side detection no longer being functional.
This patch adds a new `Warnings` field to the `/info` response. This field is
to return warnings to be presented by the user.
Existing warnings that are currently handled by the CLI are copied to the daemon
as part of this patch; This change is backward-compatible with existing
clients; old client can continue to use the client-side warnings, whereas new
clients can skip client-side detection, and print warnings that are returned by
the daemon.
Example response with this patch applied;
```bash
curl --unix-socket /var/run/docker.sock http://localhost/info | jq .Warnings
```
```json
[
"WARNING: bridge-nf-call-iptables is disabled",
"WARNING: bridge-nf-call-ip6tables is disabled"
]

Blocks the execution of tasks during the Prepare phase until there
exists an IP address for every overlay network in use by the task. This
prevents a task from starting before the NetworkAttachment containing
the IP address has been sent down to the node.
Includes a basic test for the correct use case.

This feature allows user to specify list of subnets for global
default address pool. User can configure subnet list using
'swarm init' command. Daemon passes the information to swarmkit.
We validate the information in swarmkit, then store it in cluster
object. when IPAM init is called, we pass subnet list to IPAM driver.

* Expose license status in Info
This wires up a new field in the Info payload that exposes the license.
For moby this is hardcoded to always report a community edition.
Downstream enterprise dockerd will have additional licensing logic wired
into this function to report details about the current license status.
