Title:
  Filters for DescribeInstances in EC2 API do not work

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Filters for DescribeInstances EC2 API do not work. This is a two part
  problem:

  1. describe_instances in api/ec2/cloud.py doesn't pass the arguments to _format_describe_instances
  2. Even when passing the args to _format_describe_instances, the filters don't work as described in the EC2 api

  The EC2 API describes the function this way
  (http://docs.amazonwebservices.com/AWSSDKforPHP/latest/index.html#m=AmazonEC2/describe_instances):

  $response = $ec2->describe_instances(array(
      'Filter' => array(
          array('Name' => 'project-id', 'Value' => array( 'project1', 'project2')),
      )
  ));

  When passing the arguments to _format_describe_instances, in the
  current implementation, it requires a call like this:

  $response = $ec2->describe_instances(array(
      'project_id' => array('project1', 'project2'),
  ));
