generator does not always properly qualify Aws types

[mistrmistr]

Every client created by the generator includes an executor member variable that is defined as
std::shared_ptrUtils::Threading::Executor m_executor;
due to the way C++ namespace resolution works, it would be nice if the generator could fully quality this type to Aws::Utils::Threading::Executor (include the Aws::), in case we have a conflicting Utils namespace definition (since Utils is a pretty common name for a namespace).

This is a good criticism; for similar reasons, I had to do a non-trivial amount of namespace refactoring (dropping 'using' directives) in order to get the unity/uber build option working. This should be a quick fix in the generator.

this build is being tested at the moment. It should be in the public release within the next day or so.

I was finally able to update to a newer SDK, and this problem is still there. if you look at

https://github.com/aws/aws-sdk-cpp/blob/master/aws-cpp-sdk-dynamodb/include/aws/dynamodb/DynamoDBClient.h

for example, the executor member variable is still defined as
std::shared_ptrUtils::Threading::Executor m_executor;
and not
std::shared_ptrAws::Utils::Threading::Executor m_executor;

which still causes conflicts if the surrounding code also has a namespace called Utils.
