Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.

… for `docker images`.
This deprecates the `filter` param for the `/images` endpoint and make a
new filter called `reference` to replace it. It does change the CLI
side (still possible to do `docker images busybox:musl`) but changes the
cli code to use the filter instead (so that `docker images --filter
busybox:musl` and `docker images busybox:musl` act the same).
