Fixes:#10902
AWS introduced a change to the Mount Target DNS Name to remove the
availability_zone from it -
https://aws.amazon.com/about-aws/whats-new/2016/12/simplified-mounting-of-amazon-efs-file-systems/
This was because there used to be a limit of 1 mount target per AZ -
this has been raised.

* Add ability to set Performance Mode in aws_efs_file_system.
The Elastic File System (EFS) allows for setting a Performance Mode during
creation, thus enabling anyone to chose performance of the file system according
to their particular needs. This commit adds an optional "performance_mode"
attribte to the aws_efs_file_system resource so that an appropriate mode can be
set as needed.

* Add "creation_token" and deprecate "reference_name".
Add the "creation_token" attribute so that the resource follows the API more
closely (as per the convention), thus deprecate the "reference_name" attribute.
Update tests and documentation accordingly.
