Bug fix: Ensure Fog::VERSION gets defined
OpenStack create_server mocks now match reality

Previously the mocks would return the same data as list_servers_detail.
OpenStack does not return all of this data so you must reload a server
after creation to get the necessary data when using fog for real.

Now the mock returns the same detail as the real call with the extra
detail stored in the mock data for retrieval by list_servers_detail.
Added missing HostMetrics model

Added missing HostMetrics model that wraps Host.metrics OpaqueRef.

  conn = Fog::Compute.new({
    :provider => 'XenServer',
    :xenserver_url => 'xenserver-test',
    :xenserver_username => 'root',
    :xenserver_password => 'secret',
  })

  pp conn.hosts.first.metrics # => yields

  #  <Fog::Compute::XenServer::HostMetrics
  #    reference="OpaqueRef:161923b3-47e4-7f8c-8995-3030be9d58f8",

[xenserver] Added HostMetrics tests
Added mock for Fog::Identity#get_user_by_name

OpenStack does not support filtering by name as in the real method so
the mock returns all users regardless of the name query parameter.  See:

http://docs.openstack.org/api/openstack-identity-service/2.0/content/GET_listUsers_v2.0_users_Admin_API_Service_Developer_Operations-d1e1356.html
Correct the Blue Box create_block method to check for ssh_public_key, not public_key
Removed extra whitespace from previous commit
Store the user_id in the server mock data

OpenStack returns the user_id, not the username, in the
list_servers_detail response.  This commit looks up or creates a user
to retrieve its id so it matches real OpenStack behavior.
Added SIGINT handler to the fog console

Previously ^C would exit the fog console.

Now ^C is handled and ^D, exit or quit must by typed to exit the
console.  This fixes a major personal annoyance of mine as the fog
console did not behave like IRB or like the shell when you wanted to use
^C to clear what you had just typed.
Correct the docs for the ssh_public_key option

OpenStack server test updates for real mode.

Updates to the OpenStack server tests to get things running in *real*
test mode.

This patch also adds some useful helper functions which
are now used to:
 -get the flavor ref for testing
 -get the image ref for testing
 -get the resize flavor ref for testing (defaults to flavor + 1)
 -disable password testing (not all hypervisors support this in OS)
