Add tag support to instances

[perrito666]

goamz supports filtering by tag by adding a filter with a key
prefixed by "tag." I added this behavior to the current
instance implementation in ec2test.

According to http://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeInstances.html, the format is "tag:key", not "tag.key". Your Juju PR will need to be changed too. How did it work? Does AWS accept both? Either way, please use the documented format.

It accepts both apparently but I'll go with the documented one
