Subject: [PATCH] Added precheck to check kernel version 4.2 on Ubuntu 14.04.
Kolla recommends LTS wily kernel version 4.2 on Ubuntu 14.04.
http://docs.openstack.org/developer/kolla/quickstart.html#installing-dependencies
The precheck check the running kernel version, because checking
the linux-image-generic-lts-wily cannot be a valid check.
The package (linux-image-generic-lts-wily) can be installed, but
the running kernel can be other version.
Closes-Bug: #1563500
