                                MigrateFlags sets the global flag from a local flag when it's set. This is a temporary function used for migrating old command/flags to the new format.

                                e.g. geth account new --keystore /tmp/mykeystore --lightkdf

                                is equivalent after calling this method with:

                                geth --keystore /tmp/mykeystore --lightkdf account new

                                This allows the use of the existing configuration functionality. When all flags are migrated this function can be removed and the existing configuration functionality must be changed that is uses local flags
