    Change allocation strategy for zabbix-server

    If user will use zabbix-server on node with more than one
    hard disk, and ubuntu os, it will lead to errors on provsion
    stage for the server

    Mounting /var partition on ubuntu will lead to errors
    cause there is no os volume group on ubuntu

    - add /var/lib/mysql partition, will grow most of all,
      because zabbix is using mysql for storing stats
    - change os vg to use min allocator
