add Subject Alternative Name to local openssl cert
Go 1.15 deprecates checking CN; this broke gating tests:
Get "https://localhost:5000/v2/": x509: certificate relies on legacy Common Name field, use SANs or temporarily enable Common Name matching with GODEBUG=x509ignoreCN=0
Easy two-line solution in the 'openssl' invocation. Huge
thanks to Nalin for tracking down and fixing while I was
