Replace minio-go with aws-sdk-go for s3-compatible log backend (#670)

* Logs should support specifying region when using S3-compatible object store

* Use aws-sdk-go client for s3 backed logstore

* fixes vendor with aws-sdk-go dependencies

+// Package cloud9 provides the client and types for making API
+// requests to AWS Cloud9.
+//
+// AWS Cloud9 is a collection of tools that you can use to code, build, run,
+// test, debug, and release software in the cloud.
+//
+// In the background, these tools are available through development environments
+// running on Amazon Elastic Compute Cloud (Amazon EC2) instances (known as
+// Amazon EC2 environments), your own servers (known as SSH environments), or
+// a combination. This enables you to create and switch between multiple environments,
+// with each environment set up for a specific development project.
+//
+// For more information about AWS Cloud9, see the AWS Cloud9 User Guide.
+//
+// AWS Cloud9 supports these operations:
+//
+//    * CreateEnvironmentEC2: Creates an AWS Cloud9 development environment,
+//    launches an Amazon EC2 instance, and then hosts the environment on the
+//    instance.
+//
+//    * CreateEnvironmentMembership: Adds an environment member to an environment.
+//
+//    * DeleteEnvironment: Deletes an environment. If the environment is hosted
+//    on an Amazon EC2 instance, also terminates the instance.
+//
+//    * DeleteEnvironmentMembership: Deletes an environment member from an environment.
+//
+//    * DescribeEnvironmentMemberships: Gets information about environment members
+//    for an environment.
+//
+//    * DescribeEnvironments: Gets information about environments.
+//
+//    * DescribeEnvironmentStatus: Gets status information for an environment.
+//
+//    * ListEnvironments: Gets a list of environment identifiers.
+//
+//    * UpdateEnvironment: Changes the settings of an existing environment.
+//
+//    * UpdateEnvironmentMembership: Changes the settings of an existing environment
+//    member for an environment.
