Debug deploy_model potential race

[eric-anderson]

When running aryn-opensearch.sh:deploy_model() we wait for the task to complete, however, the log message in opensearch that the model has been deployed shows up after the wait_task function returns.

Figure out if either:

1. The log messages are delayed and the task is properly finishing
2. We are waiting on the wrong task ID and there is a race on getting the model deployed that is won by opensearch because making the query via the UI is slow.
