Blocking as the role of packer is required.

[peterzhuamazon]

Block for now as we need to verify the length of macos build.
It might take over an hour to build which means the default role assume time of 1hr is not enough.

Thanks.

[peterzhuamazon]

We have confirmed all the amis can be built within 1 hr.
