Updates OWNERS files and OWNERS_ALIASES for SIG Apps

[kow3ns]

As discussed, in sig-apps, sig-architecture, steering committee, community meeting, dev ex, etc. We will attempt to clean up the OWNERS files related to SIG Apps and make the responsibilities of approvers and reviewers more general.

• kow3ns, janetkuo are included as approvers based on being TLs for SIG Apps
• soltysh, tnozicka are included as approvers based on long term contribution and active participation in this role across much of the API surface
• smarterclayton, erictune are included as emeritus contributors (both of them are approvers in higher level owners files anyway)

The next step is to clean up our contributor guidelines to make the roles, responsibilities, and contribution guidelines more clear.

Eventually I think we'll want to organize approvers and reviewers by subproject. In this case "sig-apps" is being used for the workloads-api subproject. If necessary in the future you could make it more explicit, such as "sig-apps-workloads-api-approvers".

Please take a look at the OWNERS files listed in sigs.yaml and check whether the rest should be similarly updated:
https://github.com/kubernetes/community/blob/master/sigs.yaml#L178

But this is a big improvement, so let's merge and iterate.

i strongly agree that the path is not absolutely clear, and given that development of new features is slowing. its not clear when or how can i become a approver or commiter ? Was there a discussion to define that @kow3ns ?
