Error occurs in price-feeder when reading password as file (v2.0.4)

[meetrick]

Summary of Bug

• Error occurs in price-feeder when reading password as file (v2.0.4)
  Currently, price-feeder can only be operated with systemd-service.

• In v2.0.3, price-feeder could be operated with a script that directly entered the command.
  In order to use self-monitoring and tools, a method of directly entering a command was used. Regardless of the intention of the core team, I think the function that used to work well should still work.
