dev: Limit devcontainer memory usage to 8GB (#1604)

olix0r · olix0r · commit 51ff1819401a · 2022-04-15T01:35:59.000Z
Devconatiner memory usage is currently unbounded. This allows runaway
processes (like rust-analyzer) to monopolize system resources, causing
memory exhaustion for the host OS.

This change adds a limit so that the oomkiller reaps devcontainer
processes when they exceed 8GB.
