add a retry to the test-network ccaas chaincode init command

[arner]

Without this, the init command fails if the chaincode container is not ready.

Thanks @arner , the change looks good, but you need to sign your commit for the DCO check to pass.

See:
https://github.com/hyperledger/fabric-samples/pull/1088/checks?check_run_id=16891205058

You can git commit --amend -s to sign and then re-push with -f to force push the updated commit.

Got it, done!
