Including the nested connection information in the session list response
had a negative impact on performance as it created a significant
multiplier on the number of rows that needed to be fetched from the
database.
It was also determined that this information was used by neither the
admin ui nor the desktop client.
Note that nested connection information can still be retrieved via a
read request for a specific session.
There is a new periodic job that will delete terminated sessions that
are older than one hour. However, since until now terminated sessions
were not deleted, the first time the job runs there could be a large
number of sessions that need deleted. This could have a negative impact
on a running cluster. To mitigate the operational risk, this adds a
migration to perform an initial delete while the cluster is offline.
