v1.6.0

Add `parameter_group_name_prefix_enabled` variable. Update examples and tests @aknysh (#179)

what

• Add parameter_group_name_prefix_enabled variable (defaults to true to maintain the current functionality)
• Allow using both the name and name_prefix attributes in aws_rds_cluster_parameter_group and aws_db_parameter_group resources
• Update tests to the latest versions
• Update examples to use the corerct combinations of DB instance classes and DB engine versions

why

• Allow updating old Aurora clusters, which were provisioned with the old versions of the module, to the latest version of the module without rebooting the DB instances. Old clusters, provisioned with the old versions of the module, use the name attribute (which was the only option in the old versions of the module) instead of name_prefix attribute
• Updating the parameter group causes the DB instance to reboot, which could cause a downtime. Depending on the size of the database, the downtime could take some amount of time not suitable for production clusters (after reboot, the database will go through all the recovery points and logs, and depending on the database size, it could take some time)

When you associate a new DB parameter group with a DB instance, 
the modified static and dynamic parameters are applied only after the DB instance is rebooted. 
However, if you modify dynamic parameters in the DB parameter group after you associate it with the DB instance, 
these changes are applied immediately without a reboot.
