Define unify parameter for calm get runbooks and calm get blueprint

[fabricekrebs]

The command should have as unified parameters as possible. I figured out that -s parameters for the command calm get bps specifies the offset. For the command calm get runbooks, the -o parameters must be passed to specify the offset.
