[JoshSEdwards]

Summary

• add CLI commands for health/status/metrics endpoints (ping/health/color/metrics/status/status-update)

• add CLI commands for record set extras (update, count, history, failed changes)
• add CLI commands for ownership transfer (request/approve/reject/cancel)
• add CLI commands for group/user extras (group-change, group-valid-domains, user, user-lock, user-unlock)
• add CLI commands for batch review (approve/reject/cancel)
• extend Bats suite with coverage for new commands and error-path checks

Dependency

• depends on Add missing VinylDNS API endpoints go-vinyldns#102 being merged and released before this can be built without a local go.mod replace

Manual Testing

Note: go.mod currently points at the latest released go-vinyldns. This PR depends on new client methods that are still in review in go-vinyldns PR #102, so local testing needs a temporary replace to your local go-vinyldns checkout. Do not commit this change; it is only for local testing until go-vinyldns is released.

• go mod edit -replace github.com/vinyldns/go-vinyldns=../go-vinyldns
• gmake test (starts the local VinylDNS API and runs Bats)
• optional spot checks:
  • bin/vinyldns ping
  • bin/vinyldns health
  • bin/vinyldns status --output=json
  • bin/vinyldns zone-details --zone-name ok. --output=json
  • bin/vinyldns record-set-history --zone-name ok. --record-set-fqdn some-cname.ok. --record-set-type CNAME --output=json
  • bin/vinyldns record-set-ownership-request --zone-name ok. --record-set-id <id> --requested-owner-group-id <groupId>
  • bin/vinyldns batch-change-approve --batch-change-id <id> (admin/manual review enabled)
