Provide multipath-tools package for compute node

[Kyrylo Romanenko]

While we can configure ISCSI Multipath for nova compute, we will need to install multipath-tools package manually to make Multipath work.
We can not attach volumes to instance when ISCSI Multipath enabled if multipath-tools package isn`t installed.
It`s good to prevent user from figuring-out what`s going wrong by providing multipath-tools package preinstalled on Compute node.

Hi team,

it will be good to have these packages preinstalled because this will allow to enable some OpenStack features "from the box".
Right now user should install these packages manually (and this is not documented now) to enable some OpenStack features in our product.
