How to implement client.KeysAPI

[reterVision]

I was trying to make a mock struct to do some testing with etcd API. But I get these errors:

./etcd_test.go:61: cannot use m (type *MockKeysAPI) as type client.KeysAPI in assignment:
    *MockKeysAPI does not implement client.KeysAPI (wrong type for Create method)
        have Create("golang.org/x/net/context".Context, string, string) (*client.Response, error)
        want Create("github.com/coreos/etcd/vendor/golang.org/x/net/context".Context, string, string) (*client.Response, error)

I'm on Go1.6 now and using current master branch of etcd.

Looks it can be solved if I put etcd into my vendor folder.
