[Feature Request] Use a PM2 JSON/JS configuration file instead of starting it manually

[skatcat31]

Expected Enhancement

Loading the process becomes MUCH easier to manage with a PM2 JSON since now you merely need a script to start the server by navigating to install and calling pm2 start ${file}.json

Documentation

http://pm2.keymetrics.io/docs/usage/application-declaration/#json-format

Steps to introduce

• [ ] Create and test PM2 JSON
• [ ] Update documentation
• [ ] Update deployment plans with a PM2 Save command: http://pm2.keymetrics.io/docs/usage/pm2-doc-single-page/#related-commands

Which version(s) does this affect? (Environment, OS, etc...)

Any compatible with PM2

Why?

I run several NodeJS projects that was use PM2 to manage and one of the best ways we've found to handle starting, stopping, and referring to the process is a PM2.json, since then if we don't know the name of the process, but we do know the folder, we can instead tell it to start, stop, or gracefulReload the .json file instead. It makes it easier to bring new developers into the life cycle, and often is more manageable for scripts since they are no independent of a variable name, and are instead dependent on a consistent file

@skatcat31 We already using the pm2, its just not packaged in the main repo. Instead part of seperate repo and addd during build process.

https://github.com/LiskHQ/lisk-scripts/blob/development/packaged/etc/pm2-lisk.json

We have a wrapper lisk.sh to manage the process for us, which underlying use the pm2. You can find more details on https://lisk.io/documentation/core/administration/binary

ah. Administrative repo used for full build. Makes sense. Which of the repos would be a good entry point for following from a SA point of view?
