…s/require-boto3

Update the default module requirements from python 2.6/boto to python 3.6/boto3

SUMMARY
The vast bulk of modules are now boto3 based, but some even list python2.6/boto as their requirements because they've picked the default from the aws docs fragment.
Switch the defaults over to reduce the copy&paste and reflect that

boto v2 is deprecated
python 2.6 is no longer supported by the AWS collections
