Add sleep between kcc project creation and services enablement to avoid intermittent gcloud timeout post project creation

[fmichaelobrien]

see PR #38
The setup-kcc.sh script will fail just after project creation on service enablement
755 the script first and check the folder name via #36

prereq

admin_@cloudshell:~/pdt-arg/ssc-spc-ccoe-cei/gcp-tools/scripts/bootstrap (pdt-arg)$ export PROJECT_ID=pdt-arg
admin_@cloudshell:~/pdt-arg/ssc-spc-ccoe-cei/gcp-tools/scripts/bootstrap (pdt-arg)$ export BILLING_ID=$(gcloud alpha billing projects describe $PROJECT_ID '--format=value(billingAccountName)' | sed 's/.*\///')

Without delay - error on service enablement
