api: Add a field MacAddress to EndpointSettings
Fix:

- fixes https://github.com/moby/moby/issues/34720

Related to:

- https://github.com/moby/moby/issues/31964
- https://github.com/docker/cli/pull/4419

**- What I did**

* Add a new `MacAddress` field to `EndpointSettings` ;
* Deprecate the old `MacAddress` in container's `Config` ;

**- Description for the changelog**

A MAC address can now be specified per-endpoint when creating a container.

**- A picture of a cute animal (not mandatory but encouraged)**
