Allow tags to be set on EC2 and VPC

Currently you cannot set VPC or tags on the AmazonEC2RunInstanceTask

This is problematic for us.

Seems this is the API for it from AWS http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/ec2/AmazonEC2Client.html

Also i do not see a way to get the Public DNS after an instance is up.

With my PullRequest #131 it would be possible to read the publicIP after the AmazonEC2WaitInstanceStatusTask. Perhaps a bit late, but I needed it ;-)

If someone still needs it I could also build the possibility of setting Tags for new Instances.
