NIFI-5482: Made WriteAheadProvenanceRepository the default implementation
This closes #2960.

> Make Write-Ahead Provenance Repository the default implementation
> -----------------------------------------------------------------
>
> Key: NIFI-5482
> URL: https://issues.apache.org/jira/browse/NIFI-5482
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Configuration
> Reporter: Mark Payne
> Priority: Major
> Labels: beginner, newbie
> Fix For: 1.8.0
>
>
> The default implementation for the Provenance Repository is the
> PersistentProvenanceRepository. The WriteAheadProvenanceRepository was added
> in version 1.2.0 of NiFi. We left the default as the
> PersistentProvenanceRepository only because it had been heavily tested over
> years of production use. Since then, the WriteAheadProvenanceRepository has
> proven to be not only significantly faster but also more stable and easier to
> maintain. When problems arise with the PersistentProvenanceRepository, the
> solution almost always is to change to the WriteAheadProvenanceRepository.
> Given this, we should now change the default implementation to be the
> WriteAheadProvenanceRepository.
> This involves changing the default value in the POM of nifi-resources and
> also updating the Admin Guide to note the new default and review the guide
> for any other wording that may need to be updated.
