The overlay(2) drivers were moved up in the list of storage drivers,
and are known to have problems if the backing filesystem does not
support d_type.
Commit 2e20e63da2 added a warning,
which is logged in the daemon logs, however, many users do not
check those logs, and may overlook this warning.
This patch adds the same warning to the output of `docker info`
so that the warning is more easily found.
In addition, the output of warnings printed by `docker info` is
optimized, by;
- moving all warnings to the _end_ of the output, instead of
mixing them with the regular output
- wrapping the storage-driver warnings, so that they are more
easily readable

I found that sometimes tasks would end up in a rejected state when
trying to update them quickly. The problem was that Shutdown could fail
if called before the container was started. Instead of returning an
error in this case, Shutdown should succeed. This allows tasks to
progress to the "shutdown" state as expected.

Make sure that the cursor value returned by followJournal() is the last
of the values returned by its goroutine's calls to drainJournal() by
waiting for it, rather than returning a value that may be superceded by
another if we're singalling the goroutine that it should exit by closing
a pipe.

This fix is an attempt to improve the documentation of
`Version` usage for Swarm API in Swagger docs.
As is shown in the docs updates, `Version` field in Swarm
API is a way to ensure safe concurrency and determinism
so that multiple updates to the same swarm related objects
(Node, Service, etc) will not unintentially overwrite each other.
This fix fixes 29448.
