-- | Removes the specified role from the specified instance profile.
--
-- Make sure you do not have any Amazon EC2 instances running with the role
-- you are about to remove from the instance profile. Removing a role from an
-- instance profile that is associated with a running instance will break any
-- applications running on the instance.   For more information about roles, go
-- to <http://docs.aws.amazon.com/IAM/latest/UserGuide/WorkingWithRoles.html Working with Roles>. For more information about instance profiles, go to <http://docs.aws.amazon.com/IAM/latest/UserGuide/AboutInstanceProfiles.html About Instance Profiles>.
