JDK-8214270 - Relax DNSName restriction as per RFC 1123
Description
As per parent bug :
1. DNSName only accepts letters as the first character. RFC 1123 has relaxed that restriction: 

RFC 1123, Section 2.1: 
> One aspect of host name syntax is hereby changed: the 
> restriction on the first character is relaxed to allow either a 
> letter or a digit. Host software MUST support this more liberal 
> syntax.
Comments
Fix Request Backporting this patch keeps 11u versions in sync (I see 11.0.3-oracle has it). Patch applies cleanly to 11u and passes new regression test. It also passes entire jdk_security suite.
