Revert "move RevAsync to Utils"
This reverts commit be46a0aedde1c1083374aaffc62b42d22e4d26b6.
Refactor Thespian project:
 - Protocol implementations moved to Protocols dir structure
 - Removed Actor, Extensions dirs
 - Namespace reorginisation
   - Utils namespace is public
   - Purely internal utility modules moved directly under root namespace (IOExtensions, DisposableExtensions)
 - API changes
   - Changed Utils.reraise' to something more appropriate
Refactor Thespian.Cluster project
 - RevAsync moved out from Utils to root Cluster namespace; it is absolutely core
 - ImemDb moved out from Utils to separate namespace; to be replaced by separate project
