Add support for auth providers

[wrdls]

I had to update the vendoring because azure gave errors:

make build
go fmt ./pkg/... ./cmd/...
go vet ./pkg/... ./cmd/...
# github.com/nuvo/orca/vendor/k8s.io/client-go/plugin/pkg/client/auth/azure

make: *** [Makefile:18: vet] Error 2

Note: build fails on my fork because of the imports but I don't have time right now to look into it:

Hey,

Thanks for this PR!
I would rather not using the master branch for dependencies. For uitable it is not that bad, but for the k8s related, maybe we can use a version?
Would the newest (10? Not sure) work?
If not, can we check release branch 1.13?

Thanks again :)

[wrdls]

Fair enough.

kubernetes-1.12.4 didn't work so I picked kubernetes-1.13.2 which is the latest stable release.

[maorfr]

Thanks a lot :)
I will merge that in and if all goes well i will tag it as version 0.9.2.

Glad you got involved. Let us know for any questions you have ;)
