Prevent client hanging. (OTP-8111)
Restored supervisor tree so that error propagation will work as intended, although connection processes are set to temporary, instead of permanent with restart times set to 0, and termination of the connection subtree is initiated by a temporary process spawned by ssh_connection_managers terminate. This is done to avoid unwanted supervisor reports. Pherhaps we need some new supervisor functionality.
