    Use format_message on exceptions instead of str()
    
    This patch changes all usages of unicode() and str() in the API layer
    (and most other reasonable places) into a new format_message method.
    This is done in order to avoid leaking the stack trace back to the
    user through the Remote excepitons.
    
    This patch deliberately avoids the EC2 api as the way how the EC2 API
    handles responses is being worked on as part of another blueprint.

Title:
  live-migration to an invalid host should exist gracefully. Currently,
  it throws a stack trace

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Description
  -----------
  Configure nova, boot a couple of instances, & migrate any instance to a destination (which is invalid -- no compute service on it)

     $ nova live-migration 6fdcafa3-b86b-479e-b1cf-5e6859912e65
  test1.foo.bar.com

    
  Actual results:
  --------------
  An ungraceful stack trace:
  #============================#
  $ nova live-migration 6fdcafa3-b86b-479e-b1cf-5e6859912e65 test1.foo.bar.com

  Expected results:
  --------------
  If the destination host is invalid, live-migration should exist gracefully
