Create an OWNERS file

ref: kubernetes/community#1721
ref: kubernetes/community#2464

This is listed in sigs.yaml under sig-api-machinery... but with the comment:

- name: universal-utils # There is no reason why this is in api-machinery
      owners:
      - https://raw.githubusercontent.com/kubernetes/utils/master/OWNERS

/sig api-machinery
@kubernetes/sig-api-machinery-misc
/sig architecture
@kubernetes/sig-architecture-misc-use-only-as-a-last-resort

Which SIG, if not api-machinery, does this repo (or its individual packages) belong to?

Can we get an OWNERS file at the root of this repo?

/assign @apelisse @thockin @mengqiy @dashpole
as folks who've merged PR's here in the last year

/assign @lavalamp @deads2k
sig-api-machinery chairs

[thockin]

sig-arch?

Brian has talked about a code organization subproject of sig architecture. I would put this there, as this is stuff that needs (or needed) organizing...
