This is extracted from #8094, where I have run into some snags. Since
these ESLint fixes aren’t actually connected to the Ember 3.16 update
but involve changes to many files, we might as well address them
separately. Where possible I fixed the problems but in cases where
a fix seemed too involved, I added per-line or -file exceptions.
Supports:
- Reading the head of a log
- Reading the tail of a log
- Following a log in one of two ways:
- Streaming the HTTP request (using fetch res.getReader)
- Polling the log endpoint (using EC timeouts)
