Using features in Go 1.7

[at15]

Go 1.7 is released

Features that REQUIRE changes in Ayi

• [x] improved test https://golang.org/pkg/testing/#hdr-Subtests_and_Sub_benchmarks Though things like tear down is already support in testify and Ayi does not require much of bench mark :)
• [x] https://golang.org/pkg/context/ context allow better control of cancel execution etc. But I am not sure I understand it clearly.

  Features that does NOT require changes in Ayi

• vendor. ( we are already using vendor )
