6945a712df limit node memory usage
node needs to be told how much space it can usage, otherwise it keeps
allocating and we cannot keep it under 50M. keeping old space to 30M,
lets the memory hover around 40M

there are many options to v8 but I haven't explored them all:
--expose_gc - allows scripts to call gc()
--max_old_space_size=30 --max_semi_space_size=2048 (old/new space)
    node first allocates new objects in new space. if these objects are in use
    around for some time, it moves them to old space. the idea here is that it
    runs gc aggressively on new space since new objects die more than old ones.

    the new space is split into two halves of equal size called semi spaces.

--gc_interval=100 --optimize_for_size --max_executable_size=5 --gc_global --stack_size=1024

note: this is not part of shebang because linux shebang does not support args! so we cannot
pass node args as part of shebang.

e76584b0da Move from supervisor to systemd
This removes logrotate as well since we use systemd logging
