Nifi 4993 null user
## For reviewer(s)
Please be aware that there is another major issue with 'complete path'
strategy, that is #2542. It should be easier to confirm this fix if that PR is
cherry-picked as well when you review this PR (in case if that one is not
merged yet to master branch when you review this one).

Before this fix, if provenance lineage is qualied by a user who does
not have 'view the data' plivilege for a component which emits
provenance events those create new FlowFile, then lineage computation stops
at such component, instead of connecting other available events with
the created FlowFile lineage node. Expected edges are not created
because PlaceholderProvenanceEvent returns 'UNKNOWN'
event type, edge population logics relying on that type do not work.
This PR modifies existing provenance repository implementations to accept
'null' NiFi user so that NiFi internal component can query lineage without NiFi
user and authorization.
