Maintenance release including mainly fix for virtual
database shutdown bug in distributed mode and connection pool managers
bugs (RandomWaitPoolConnectionManager and VariablePoolConnectionManager).
# Fixed OctopusBackuper that deleted dumps dir
# Fixed RandomWaitPoolConnectionManager synchronization that was broken in
2.0.1. Problem reported by Michael Plezbert.
# Fixed virtual database shutdown in distributed mode where backends were not
disabled on the last remaining controller in the cluster.
# Fixed controller shutdown problem in SAFE and FORCE modes that would
fallback to WAIT mode and terminate the recovery log before disabling the
# Fixed synchronization problem in VariablePoolConnectionManager that would
prevent its correct termination. Also fixed release time inconsistencies
reported by Ray Matthes.
