Revoke Engineering Leaders Access to VPC Related actions in tvlk-dev

Currently we grant PowerUser privileges to engineering-leaders group in tvlk-dev.

To ensure stability of test VPC and to prevent Engineering Leader (which has PowerUser privilege ) from accidentally changing VPC related settings / resources, site infra is about revoking VPC related action that applied on Engineering Leader IAM group.

Details available on TOSD-845

If you suddenly cannot do something that might be impacted by this new IAM policy please let @site-infra know.

Thank you.
