SDK compilation fails for some updated services

[dagnir]

Expected Behavior

Updated service models should compile without error.

Current Behavior

The current models (e.g. as can be found in https://github.com/boto/botocore/tree/develop/botocore/data) for s3, rds, ssm, mediapacakge, cognitoidentityprovider do not build in V2. The issues differ for each service:

• s3
  There are some issues around generation of eventstreaming operations.
  Excluding them using customization.config doesn't seem to work since the
  (un)marshallers are still being generated.

• rds
paginators-1.json excluded due to compilation errors.

• ssm
  Compilation errors compiling model objects.

• mediapackage
'Name cannot be null or empty' error during codegen.

• cognitoidentityprovider
  New model has a Notify member that classes with Object#notify. Will
  include in a separate PR (The EC2 member rename is included here since there's
  already precedent for it in other shapes/operations).

Possible Solution

Steps to Reproduce (for bugs)

pull in the service-2.json and paginators-1.json for the given service from https://github.com/boto/botocore/tree/develop/botocore/data and compile the module.
