df21a972b6 nsjail: Optionally forward fatal signals
Currently, we always kill children by sending them a SIGKILL signal in
case we've got a fatal signal. This is rather inflexible and forbids
some usecases where e.g. child process listen for specific signals to
shut down gracefully.

Add a new command configuration `--forward_signals` that allows the user
to opt-in to forwarding fatal signals to the child process.

Fixes #146: cgroups_mem_max unit in config.proto
This commit fixes the incorrect cgroups_mem_max unit described in a config.proto comment.

We do not perform any calculations on this value and we don't specify the values unit (k/M/G) when writing to memory cgroup controller files, so the value is specified in bytes.

Fix default rlimit_stack value
The default `rlimit_stack` value was set to 1048576. However, this value is in MiB and so is later multiplied by 1024*1024 in b3d544d155/config.cc (L161-L162) and it ends up as a limit of 1 TB for the stack size.

This PR changes it to 8 MB which is a more sane default or, at least I took it from my virtual machine's ulimits:
```
$ ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 31175
max locked memory       (kbytes, -l) 16384
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 31175
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited
