aws-ec2-assign-elastic-ip (go)

This is a clone of discobean/aws-ec2-assign-elastic-ip inspired from skymill/aws-ec2-assign-elastic-ip except that:

1. It is written in go
2. Allows to select from a Pool of EIPs by using tag key/values

Usage (instanceid/region from metadata):

./aws-ec2-assign-elastic-ip-darwin-amd64 
    --tag-name Application 
    --tag-value minecraft 

Usage (when specifying instanceid/region):

./aws-ec2-assign-elastic-ip-darwin-amd64 
    --tag-name Application 
    --tag-value minecraft 
    --region ap-southeast-2 
    --instanceid i-0f0e97a20a05ce74b
