Local fix

Problem summary

• PkSsCertFactory.newSsCert() API generate error when a
  certificate is created having SubjectAlternativeNames starts
  with asterisk or digit.
  Key Certificate Management fails to create a certificate
  containing a Subject Alternative Name (SAN) DNSName value that
  does not begin with a letter.
  A certificate attribute was not recognized when SAN DNS value
  begins with asterisk or digit. It occurred because of relaxation
  not yet provided as per RFC 1123 for Key Certificate Management.
  

Problem conclusion

• Key Certificate Management has been updated to accept relaxed
  DNSName specifications as per RFC 1123. SAN DNS can begin with
  asterisk or digit.
