node-red-daemon append arguments

[kaffetorsk]

• [ ] Bugfix (non-breaking change which fixes an issue)
• [x] New feature (non-breaking change which adds functionality)

Proposed changes

Added the possibility of specifying additional arguments when manually starting the process with msg.start. Arguments specified in msg.args will be appended to the arguments already configured. This allows for template commands.
