Che: Not enough default memory limit for typescript remote plugin

[AndrienkoAleksandr]

Description

Not enough default memory limit for typescript remote plugin. We have default sidecar container memory limit https://github.com/eclipse/che/blob/master/assembly/assembly-wsmaster-war/src/main/webapp/WEB-INF/classes/che/che.properties#L105. But typescript sidecar plugin need more RAM value.

Reproduction Steps

1. Create workspace from devfile:
   https://github.com/eclipse/che/blob/caae00e21b2fd316560a406f2e1d8ad98edf1dad/workspace-loader/devfile.yaml
   
2. Start workspace.

Actual result: workspace started, but che-theia is not avaliable. Instead of IDE editor, we see an error:
503 Service Temporarily Unavailable
nginx/1.15.9

If I apply memory lmit 340M in the devfile - workspace became working again.
Expected result: workspace should starts and open IDE editor.

OS and version:
Kubuntu 19.04 che-server 7.0.0-RC-2.0-SNAPSHOT

@AndrienkoAleksandr wasn't the limit 512m until recently?

@tsmaeder 512Mb really was, some time ago... https://github.com/eclipse/che/commit/a0a722f650afcdaf58f5d1d9f02652ed506dcf21

@slemeur @tsmaeder looks like it's still actual.

You can use the following sample app to test https://github.com/sleshchenko/NodeJS-Sample-App

Can we prioritize this issue and find a proper default memory limit for typescript LS?

[tsmaeder]

As I've written in my message to the che-dev mailing list a week ago , my team (in particular @tolusha) is addressing default memory sizing in this sprint.
We will use the examples from the stacks to set the default memory sizes for the sidecars.
