Add docker volumes janitor
...
This cleans up tmp and logrotates /var/log every 12 hours.
Note that this janitor is separate from the box janitor because they
run as different users.
Fixes #503

Merge apphealthtask into box server
...
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.

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.
