[Blueprint servercloud-p-arm-service-orchestration] Enabling juju for ARM

Whiteboard changed:
  Question:
  Is this using juju for direct deployment, or via Orchestra? -- Daviey
  
  Via Orchestra. I think the main thing to test is juju because of it's
  reliance on java with zookeeper. We don't need to discuss anything, just
  test and fix bugs. -- Robbie
  
  For juju to work on ARM, I am assuming that:
  
  1. ARM hardware will support IPMI for power management
  2. ARM hardware will support pxelinux emulation for boot
  3. cobbler's existing IPMI support will work with ARM IPMI
  
  Status:
- There are two modes of operation: running juju in a local environment, and running juju via orchestra. juju currently fails to run on ARM in a local environment, and I am working on this - but this is blocking me from clearing the first five work items. Now that I have three pandas, I can test juju via orchestra also. I expect either to clear the first four work items as soon as I get juju working like this, or to find a series of ARM-specific bugs that I will need to fix first.
+ The announcement of MAAS is exciting for the ARM Server story, as MAAS is exactly what ARM servers need! As MAAS will have replaced or enhanced cobbler and orchestra by the time ARM server hardware is generally available, it now makes more sense to work on MAAS on ARM directly. In line with the expected ARM server hardware delivery timetable, this is a task for Q, so I've postponed work items appropriately.
