Dex: Migrate from TPRs to CRDs

[alonl]

Hi guys, and thanks for the great work.

Are there any plans for supporting Kubernetes version 1.7 and above?

In Kubernetes 1.7 ThirdPartyResource API (which, AFAIK, Dex uses) has become deprecated, and in Kubernetes version 1.8 it'll be removed (see Changelog), so Dex must migrate to CustomResourceDefinition. Documentation here.

I couldn't find any issue on this topic...

Hey @alonl we've been planning this migration internally, but haven't migrated it to the open source repo yet. So yes there are plans. Thanks for opening!
