Add control for creating and attaching policies

[rnikoopour]

Issue:
I am unable to use an existing role with policies managed outside of the module.

Description:
By adding a new input called create_policies the module users can control whether the policies in the module are created an attached.

Also ran terraform format against the two files worked it.

Additional Info:
create_policies defaults to true so there should be no impact to existing users.
