aws labs is now at https://github.com/jclouds/jclouds-labs-aws

With jclouds 1.6.0 final out, we can now move development of aws into its new home at https://github.com/jclouds/jclouds-aws-google

This will be a temporary place until it is merged into an apache repository per issue #1576

Note I've setup buildhive pull request hooks and will setup snapshot publishing as soon as this is merged.

commands I used to create the new repo off master:
```
git clone https://github.com/jclouds/jclouds-labs.git
git filter-branch --prune-empty --subdirectory-filter aws master
git push -f https://github.com/jclouds/jclouds-labs-aws.git master
```
I followed that up with a cleanup of pom.xml and added default README.md and .gitignore
