1. ci-operator: Fresh AWS shared subnets for us-east-2, etc. …

   ci-operator/templates/openshift/installer: Replacement shared subnets for new regions
   
   I'd created the previous subnets in
   7e38260 (ci-operator/templates/openshift/installer: Shared
   subnets for new regions, 2020-01-23, openshift#6845), but forgot to add
   them to the reaper whitelist [1].  So the reaper just removed my
   old subnets.  Recreating them here:
   
     $ export AWS_PROFILE=ci  # or whatever you call it locally
     $ git fetch origin
     $ date --iso=m --utc
     2020-01-30T17:09+0000
     $ git checkout origin/release-4.3
     $ git --no-pager log --oneline -1
     2055609f9 (HEAD, origin/release-4.3) Merge pull request openshift#2928 from ashcrow/4.3-signed-rhcos-bump
   
   Clear out the old stacks:
   
     for REGION in us-east-2 us-west-1 us-west-2
     do
       COUNT=3
       if test us-west-1 = "${REGION}"
       then
         COUNT=2
       fi
       for INDEX in 1 2 3 4
       do
         NAME="do-not-delete-shared-vpc-${INDEX}"
         aws --region "${REGION}" cloudformation delete-stack --stack-name "${NAME}"
         aws --region "${REGION}" cloudformation wait stack-delete-complete --stack-name "${NAME}"
       done
     done
   
   I had to lean in manually and delete some instances in us-west-2's
   do-not-delete-shared-vpc-4 to unstick it.  Then create the new
   subnets:
   
     for REGION in us-east-2 us-west-1 us-west-2
     do
       COUNT=3
       if test us-west-1 = "${REGION}"
       then
         COUNT=2
       fi
       for INDEX in 1 2 3 4
       do
         NAME="do-not-delete-shared-vpc-${INDEX}"
         aws --region "${REGION}" cloudformation create-stack --stack-name "${NAME}" --template-body "$(cat upi/aws/cloudformation/01_vpc.yaml)" --parameters "ParameterKey=AvailabilityZoneCount,ParameterValue=${COUNT}" >/dev/null
         aws --region "${REGION}" cloudformation wait stack-create-complete --stack-name "${NAME}"
         SUBNETS="$(aws --region "${REGION}" cloudformation describe-stacks --stack-name "${NAME}" | jq -c '[.Stacks[].Outputs[] | select(.OutputKey | endswith("SubnetIds")).OutputValue | split(",")[]]' | sed "s/\"/'/g")"
         echo "${REGION}_$((INDEX - 1))) subnets=\"${SUBNETS}\";;"
       done
     done
   
   7e38260 had a us-east-1 typo in the commit message, fixed
   here.  I actually used us-east-2 in that commit as well, and just
   fumbled the copy into the old commit message.  Creation spit out:
   
     us-east-2_0) subnets="['subnet-0a568760cd74bf1d7','subnet-0320ee5b3bb78863e','subnet-015658a21d26e55b7','subnet-0c3ce64c4066f37c7','subnet-0d57b6b056e1ee8f6','subnet-0b118b86d1517483a']";;
     ...
     us-west-2_3) subnets="['subnet-072d00dcf02ad90a6','subnet-0ad913e4bd6ff53fa','subnet-09f90e069238e4105','subnet-064ecb1b01098ff35','subnet-068d9cdd93c0c66e6','subnet-0b7d1a5a6ae1d9adf']";;
   
   To generate the reaper whitelist [1], I used:
   
     for REGION in us-east-1 us-east-2 us-west-1 us-west-2
     do
       for INDEX in 1 2 3 4
       do
         NAME="do-not-delete-shared-vpc-${INDEX}"
         aws --region "${REGION}" resourcegroupstaggingapi get-resources --tag-filters "Key=aws:cloudformation:stack-name,Values=${NAME}" --query 'ResourceTagMappingList[].ResourceARN' | jq -r ".[] | split(\":\")[-1] | \"                '\" + . + \"',  # CI exclusion per DPP-4108, ${REGION} ${NAME}\""
       done
     done | sort
   
   followed by some whitespace shuffling to get the comments aligned.
