Intent to backport OAK-{7168,7169,7171} to 1.8

[Francesco Mari]

I intend to backport OAK-{7168,7169,7171} to the 1.8 branch. The three
issues fix the behaviour of the debug, datastorecheck, and history
command when it comes to error handling. The fix make these commands
return with a non-zero exit code in case of error and print error
message to standard error instead of standard output.
