add new samples
examples for opsworks, redshift, s3
Move examples into awscli/examples

No longer needs to be in doc/source/examples
Move ec2 examples over to awscli/examples
Move IAM examples over to awscli/examples
Move sns/sqs examples over to awscli/examples
Move s3 examples over to awscli/examples
Grab examples from the awscli/examples

Use package_data the same way we're using it for
the .json files.

Also examples/*/* is how we specify the files.
This will need to change if we have directory
structures that nest more deeply than this.
