Support typescript with pm2

[samreid]

From phetsims/chipper#1481, https://pm2.io/docs/runtime/integration/transpilers/#typescript%5C describes how we can launch typescript scripts via pm2.

Until we upgrade, these entry points and their dependencies are stuck as *.js.

I'm hitting this in phetsims/aqua#219. It is very easy to support this with sage run with this:

args: 'run . . .',
script: '../perennial/bin/sage',
interpreter: '/bin/bash',

The issue is that this only runs well in fork mode, it won't work for our clustered code, like ct-puppeteer-client. I learned about this here:

https://stackoverflow.com/questions/34682035/cluster-and-fork-mode-difference-in-pm2.

I'll keep investigating.

From this I believe that to support cluster mode, we will be required to transpile the typescript into javascript before supporting cluster mode.

I believe this is relatively close. I restarted all bayes processes to run with sage run, and it is working well!

[zepumph]

Yes. I believe this is ready to close! Sparky and Bayes are both running tasks with sage run with a bash interpreter.
