New boot driver interface

Registered by Lucas Alvares Gomes on 2014-10-06

The "deploy" driver interface is responsible for two things in Ironic right now: Booting and provisioning the node, these are separated functions and therefor should be abstracted separately to make drivers more flexible and avoid code duplication.

This blueprint is proposing splitting the boot part of the deploy interface into its own interface, a "boot" interface.

Example of boot methods:
- PXE
- OOB Virtual Media

Example of deploy methods:
- iSCSI
- IPA

Due to time constraints to review the code, the iLO and iRMC updates couldn't make it into Liberty and should be prioritized in Mitaka.
