[sassdavid]

Hello,
me again :)

Another policy change is needed to use the 2.11.0 version of the load balancer controller.

Description

• update IAM policy document according to official docs
• this is not a breaking change just an option to upgrade to 2.11.0

Type of change

• A bug fix (PR prefix fix)
• A new feature (PR prefix feat)
• A code change that neither fixes a bug nor adds a feature (PR prefix refactor)
• Adding missing tests or correcting existing tests (PR prefix test)
• Changes that do not affect the meaning of the code like white-spaces, formatting, missing semi-colons, etc. (PR prefix style)
• Changes to our CI configuration files and scripts (PR prefix ci)
• Documentation only changes (PR prefix docs)

How Has This Been Tested?
