[NFR] Add filesystem quotas for each user

[joglomedia]

Limit the amount of disk space a user or group can use on a filesystem. Without such limits, a user could fill up the machine’s disk and cause problems for other users and services.

apt-get update
apt-get install quota

## Install kernel quota modules.

if find /lib/modules/$(uname -r) -type f -name '*quota_v*.ko*' > /dev/null 2>&1; then
    echo "Kernel quota modules already exists";
else
    echo "Kernel quota modules not found. Installing...";
    apt-get install linux-image-extra-virtual
fi
