initially, i thought i can hardcode the log file into taskworker.js
depending on the task type but for apptask, it's not easy to get the
appId from the taskId unless we introspect task arguments as well.
it's easier for now to pass it as an argument.
Simple Auth used to provide auth over HTTP. The original motivation
behind this was this was a simple way to add Cloudron Auth integration.
Back in the day, Cloudron Auth was a requirement for apps but this is
not the case anymore.
This is currently not used by any app and having this might encourage
people to make Cloudron specific un-upstreamable changes.
We used to run this as a separate process but no amount of node/v8 tweaking
makes them run as standalone with 50M RSS.
Three solutions were considered for the memory issue:
1. Use systemd timer. apphealthtask needs to run quiet frequently (10 sec)
for the ui to get the app health update immediately after install.
2. Merge into box server (this commit)
3. Increase memory to 80M. This seems to make apphealthtask run as-is.
