Update to go 1.12.2 testing.

Fixes #10528

[hexfusion]

I think this needs to be explicitly 1.12.2

[spzala]

Cool, thanks @hexfusion

[spzala]

@hexfusion @gyuho I don't see any issue with build, format or unit test in my env. Thanks!

[gyuho]

Did we build and push the Go 1.12 based test image?

@gyuho nope, not yet. That's where @hexfusion needs to help out :-)

[hexfusion]

@spzala thanks for your patience test image is up

@hexfusion @gyuho issue in Kube related to 1.12 https://groups.google.com/d/msg/kubernetes-dev/jmxp5ceglnY/qU7ufaLACQAJ and kubernetes/kubernetes#75833

[spzala]

The failure I see in build is fmt related and this error
gosimple checking failed: Gosimple has been deprecated. Please use staticcheck instead. @gyuho already have patch #10441 under review to remove deprecated packages with staticcheck. Hopping that PR should take care of the failure here..is there anything holding for that PR to be merged? I have one review comment there. Thanks!

[gyuho]

@spzala Can you take over #10441?

@spzala Can you take over #10441?

@gyuho thanks and sure that sounds good! I am at a local conference in Raleigh today all day but will get back to work soon :-)

[spzala]

@gyuho @hexfusion I have created #10631 (merged this PR and #10441) I will keep this PR open as WIP but will close eventually in favor of the new PR if that makes sense. Thanks!

[spzala]

@gyuho @hexfusion closing this one since we have Go 1.12.5 update in place under #10766 and we are doing test related updates in another PR as mentioned above. Thanks!
