Update controller-tools and CRDs

[rifelpet]

The make crds task is currently broken on master because:

1. controller-tools is no longer in the vendor directory after the switch to go mod. The tools.go addition fixes that.
2. controller-tools 1.1.0 was depending on a conflicting version of the k8s.io/api and needed updating to the very latest commit in order to pick up support for 1.15.

Marking WIP because i haven't had a chance to actually test the CRDs yet and do a structural yamldiff to look for any unexpected changes.

Thanks for doing this. Two things:

• I think we need 🐛 promote version-specific CRD fields when only one version kubernetes-sigs/controller-tools#322 in controller-tools, so that the CRDs can then be installed on 1.16 (otherwise we hit Single-version generated CRDs cannot be installed kubernetes-sigs/controller-tools#302). I did GO111MODULE=on go get -u sigs.k8s.io/controller-tools@76a25b63325ae000dd90099b151b196ac55979ac A nice side effect of this is that the CRDs are then recognized as renames and the diff is more comprehensible.

• I'm changing float -> resource.Quantity in the other series of PRs, to avoid the warnings from the generator. I'm not 100% sure whether they are just warnings i.e. are the fields just ignored.

Thanks for the suggestions! I'm still fighting some dependency version compatibility issues, but the new CRD yamls are looking much better. I'll try to get the remaining issues addressed soon.

@justinsb reran the go get and everything worked better this time :) CRD diffs are looking good overall too
