so ansible_distribution_major_version is defined an there is no need to default it

* Add extra tolerations for coredns

* dns_extra_tolerations option

* dns_extra_tolerations

* missing starting space in comment

Initially this was to fix a mis-indented approvers key. However, it turns
out that 'oilbeater' is not a member of kubernetes-sigs nor
kubernetes-incubator (the org this repo was migrated from). Thus this
OWNERS file is failing prow's validation check.

As a workaround I've opted to move them to emeritus_approver, which
isn't valiated and can be used as a hint for other approvers in this
repo
