No IPAM IPv6 address is given to an interface in a network with
'--ipv6=false', but the kernel would assign a link-local address and,
in a macvlan/ipvlan network, the interface may get a SLAAC-assigned
address.
So, disable IPv6 on the interface to avoid that.

We document that an macvlan network with no parent interface is
equivalent to a '--internal' network. But, in this case, an macvlan
network was still configured with a gateway. So, DNS proxying would
be enabled in the internal resolver (and, if the host's resolver
was on a localhost address, requests to external resolvers from the
host's network namespace would succeed).
This change disables configuration of a gateway for a macvlan Endpoint
if no parent interface is specified.
(Note if a parent interface with no external network is supplied as
'-o parent=<dummy>', the gateway will still be set up. Documentation
will need to be updated to note that '--internal' should be used to
prevent DNS request forwarding in this case.)

Integration tests will now configure clients to propagate traces as well
as create spans for all tests.
Some extra changes were needed (or desired for trace propagation) in the
test helpers to pass through tracing spans via context.

The linter marked an issue because testMacvlanMultiSubnet was not used.
Re-enabling the test showed that there was a typo in the assert, causing the
test to fail:
```
--- FAIL: TestDockerNetworkMacvlan/MultiSubnet (4.74s)
macvlan_test.go:243: assertion failed: 2001:db8:abc4::254 (c3.NetworkSettings.Networks["dualstackbridge"].IPv6Gateway string) != 2001:db8.abc4::254 (string)

The daemon requires kernel 3.10 or up to start, so there's no need
to check if the daemon is kernel 3.8 or up.
