Em Sharnoff cc29def544 vm-monitor: Ignore LFC in postgres cgroup memory threshold (#8668)
In short: Currently we reserve 75% of memory to the LFC, meaning that if
we scale up to keep postgres using less than 25% of the compute's
memory.

This means that for certain memory-heavy workloads, we end up scaling
much higher than is actually needed — in the worst case, up to 4x,
although in practice it tends not to be quite so bad.

Part of neondatabase/autoscaling#1030.
