[ashishdhingra]

Per TagResource, the operation requires permissions for the elasticfilesystem:TagResource action. Also per AWS managed policies for Amazon EFS, all the Action(s) are prefixed with elasticfilesystem: (not efs).

Updates the iamServiceMap that maintains list of services having mapping to IAM policy prefix names.

Description of how you validated changes

Added unit test and integration test (along with snapshot).
