Retry dataset publication on awaiting indexing failure

[PaulBoon]

Fixes DD-1433

Description of changes

When a dataset publish is requested with the option to assure indexing, the result might be a failure 409 status code.
This PR will then try to publish again, with a delay and a maximum number of retries.
If another failure happens or the max retries is reached without success, the publish fails.

Looks good. I am having a hard time reproducing the problem that this solves, though.
