Fuel tries to boot nodes via eth0 even if PXE interface differs

[Andrew Lazarev]

Steps to repro:
1. Configure eth0 and eth5 for nodes
2. Set up eth5 as PXE interface
3. Reboot nodes via PXE on eth5 manually. Fuel will discover them as nodes.
4. Configure system in Fuel UI
5. Check networking in Fuel UI - no errors found
6. Click "Deploy"

Expected behavior: Fuel installs OpenStack cluster
Observed behavior: Fuel waits nodes to reboot via PXE. Nodes tried to reboot using PXE on eth0 and finish with boot from HDD. Fuel UI shows 0% progress. Manual reboot of nodes with selection eth5 helps.

Reason: nodes have eth0 as default boot inerface in BIOS.

Solution:
1. if it is possible - change BIOS setting (IPMI commands?)
2. if it is not possible - document such scenario

For the vast majority of systems, we can't control the boot order of bare metal systems. Automated IPMI configuration is not a part of Fuel at this time, so this responsibility is on the local administrator to enable proper PXE boot behavior.

The documentation related to this is here: http://docs.mirantis.com/fuel/fuel-5.1/user-guide.html?highlight=boot#boot-the-node-servers

[Andrew Lazarev (alazarev)]

"Then you can boot each node (other than the Fuel master) in PXE boot mode by either modifying the BIOS boot order or using F12 (or another key your server uses) to enable PXE booting"

I think we should add note "If you PXE not from eth0 make sure that node will be booting from the right network."

[Andrew Lazarev (alazarev)]

Or even "if you have several network interfaces ..."

    Improve wording around PXE booting nodes

    This commit includes some minor changes in
    wording regarding PXE booting, specificically
    reminding the reader to consider which network
    the node will PXE boot from.
