commands: add value for cmdtype argument for read only commands
In the previous release we added an argument `cmdtype` to registrar.command()
which is a enum and tells whether the command is read only, recoverable write or
unrecoverable write command. This patch add the value of cmdtype argument for
commands which are read only.
