[RFE] Add support for partition images in agent driver

[Vladyslav Drok]

This proposal suggests to enhance agent driver to support deploy using partition images. After the deploy, the subsequent reboot of the node will happen either through pxe or vmedia, depending on the boot method chosen by the driver.
