Updates

Mostly some fixes I added for my own use, but figure I'd share them back

• Deploy certificate to same region as CloudFormation stack (previously seems to be hardcoded)
• Allow Setting Log Level from CloudFormation Stack/Reduce default log level
• Do not fail if SubjectAlternativeNames is an empty list. Support empty items
  in SubjectAlternativeNames list. (previously i got errors if SAN list was empty)
