Make the creation of the primary index in Couchbase container retryable

[vincz777]

When starting the CouchbaseContainer sometimes this error occurs:

Apparently the database is rebalancing, preventing the creation of the primary index.

We propose to make the creation of the primary index retryable, as many other operations occuring during the set-up of the container.
