Upgrade Notes

`aws-sdk` - v3.0.0

An equivalent gem of aws-sdk that provides resource oriented interfaces and other higher-level abstractions for many AWS services. Please see the V3_UPGRADING_GUIDE.md guide for upgrading details.

Service modules have been removed from aws-sdk-core. They are now available in service gems. The aws-sdk-core gem now only contains shared utilities, such as credential providers, logging, etc. If you had a dependency on aws-sdk-core previously to use Amazon S3, replace it instead with aws-sdk-s3. If you want to load every AWS service gem, use the aws-sdk gem.
Moved the aws.rb REPL from the aws-sdk-core gem into the aws-sdk gem.
Aws.eager_autoload! is deprecated as all autoload statements have been replaced with require statements. Calling this method will now generate a warning and have no other effect.
Removed the Aws.add_service method. Services are no longer defined at runtime. Each service is now defined in a seperate gem, e.g. aws-sdk-s3, aws-sdk-ec2, etc.
Preview Gem aws-sdk-sfn is deprecated, use aws-sdk-states instead.
Preview Gem aws-sdk-lexruntimeservice is deprecated, use aws-sdk-lex instead.
