golang DNSSEC key creation creates invalid keys

[dneuman64]

When DNSSEC keys are created by the golang route they are invalid and choke TR. It looks like the domain name is being generated with two periods at the end which is causing the issue.

Example: "name": "neuman-test.cdn.domain.com..", "expirationDate": 1535907835, "inceptionDate": 1533315835, "effectiveDate": 1533315835,

which causes this error in TR:
