pxe: Moving logs into /var/log/edeploy/
pxe: Moving logs into /var/log/edeploy/

When the OS is deployed, some information were put into /var/log.

Let's move them to /var/log/edeploy to get more readability of what is
related to edeploy.

This patch also add some new logs :
- the configure script (useful to understand what was supposed to be
  done)
- the dmesg (to get the kernel log during the deployment)
