Enable vendoring using GOVENDOR

Resolves - https://discuss.dgraph.io/t/vendoring-dependencies-for-dgraph/177

Pertaining to the discussion mentioned above: GLOCKFILE has been removed,
README has been updated, and vendor/vendor.json has been added. At this
point of time we are only adding dependency information file(vendor.json) and
not the actual dependencies. This commit also helps avoiding
installation of dependencies in $GOPATH if vendor directory is synced
using govendor.

+Now get [DGraph](https://github.com/dgraph-io/dgraph) code. DGraph uses `govendor` to fix dependency versions. Version information for these dependencies is included in the `github.com/dgraph-io/dgraph/vendor` directory under the `vendor.json` file.
