Fix property ownership revisit bug in ConsistencyChecker

The consistency checker would mistakenly think that a previously determined owner was a duplicate of itself, when `consistency_check_property_owners` was enabled, leading to many false positives.

This fixes #3275

Abbreviate common connection closed error.

When the client closes a connection to the server before recieving the full
reply, the server currently prints a lengthy stack trace to the log. This
stack trace is not helpful, because we already do the right thing here.

Replace stack trace with one-line log message noting the client closed the
connection.

Fixed issue with cancelling long running queries in server.

JsonGenerators were not properly closed in finally blocks which lead to
malformed json when queries were cancelled by the user.

Introduce debug capability for request content logging.

Currently undocumented, this introduces experimental support for logging
full request and response bodies. This is currently enabled by setting:

    org.neo4j.server.http.unsafe.content_log.enabled=true

In neo4j-server.properties, and by specifying the http log to output full
requests and responses:

    <pattern>%fullRequest\n\n%fullResponse</pattern>

As this uses mechanisms to fully duplicate incoming request and response
streams, it is strongly recommended to not run this in a production setting.
However, it should prove very useful for debugging and testing.
