Fixes an issue where terraform plan or apply will always have a diff.
The Elastic Beanstalk API returns data for the `resource` attribute for
some settings that are not documented. This limits the `resource`
attribute to settings in the `aws:autoscaling:scheduledaction`
namespace.
* Updated `aws_elastic_beanstalk_environment` to update environment when the `template_name` attribute has a change. Consildated update functions to use a single update call and added state change conf to wait until environment is in a "Ready" state.
* Adding tests for `aws_elastic_beanstalk_configuration_template` use with the `aws_elastic_beanstalk_environment` resource.
* Verifies option settings from an `aws_elastic_beanstalk_configuration_template` resource are applied to the associated `aws_elastic_beanstalk_environment` resource
* Verifies updated name of an `aws_elastic_beanstalk_configuration_template` resource triggers an update for the associated `aws_elastic_beanstalk_environment` resource
* Verifies that option settings set in the `aws_elastic_beanstalk_environment` resource override settings in the `aws_elastic_beanstalk_configuration_template` resource
This adds support for Elastic Beanstalk Applications, Configuration Templates,
and Environments.
