a lot of fixes:
 - changed default key size to 2048
 - added support for IP SANs
 - fixed generated keystore for ssl - only one entry is added but with cert chain - now netty is serving proper certificate chain
 - changed constant serial version for certificates - now are generated base on time

 - CA certificate is now version 3 - thanks to that isCA extension is added
 - fixed bug with domainName SAN - substring with .
 - default CN of server ssl certificate set to localhost
