comment of the host index api is incorrect

[Lingxian Kong]

Just a little nit, the comment of the host index api in the source code(the formatted version):

{
 'hosts': [{
  'host_name': 'some.host.name',
  'service': 'cells',
  'zone': 'internal'
 },
 {
  'host_name': 'some.other.host.name',
  'service': 'cells',
  'zone': 'internal'
 },
 {
  'host_name': 'some.celly.host.name',
  'service': 'cells',
  'zone': 'internal'
 },
 {
  'host_name': 'console1.host.com',
  'service': 'consoleauth',
  'zone': 'internal'
 },
 {
  'host_name': 'network1.host.com',
  'service': 'network',
  'zone': 'internal'
 },
 {
  'host_name': 'netwwork2.host.com',
  'service': 'network',
  'zone': 'internal'
 },
 {
  'host_name': 'compute1.host.com',
  'service': 'compute',
  'zone': 'nova'
 },
 {
  'host_name': 'compute2.host.com',
  'service': 'compute',
  'zone': 'nova'
 },
 {
  'host_name': 'sched1.host.com',
  'service': 'scheduler',
  'zone': 'internal'
 },
 {
  'host_name': 'sched2.host.com',
  'service': 'scheduler',
  'zone': 'internal'
 },
 {
  'host_name': 'vol1.host.com',
  'service': 'volume'
 },
 'zone': 'internal']
}

which should be:

{
 'hosts': [{
  'host_name': 'some.host.name',
  'service': 'cells',
  'zone': 'internal'
 },
 {
  'host_name': 'some.other.host.name',
  'service': 'cells',
  'zone': 'internal'
 },
 {
  'host_name': 'some.celly.host.name',
  'service': 'cells',
  'zone': 'internal'
 },
 {
  'host_name': 'console1.host.com',
  'service': 'consoleauth',
  'zone': 'internal'
 },
 {
  'host_name': 'network1.host.com',
  'service': 'network',
  'zone': 'internal'
 },
 {
  'host_name': 'netwwork2.host.com',
  'service': 'network',
  'zone': 'internal'
 },
 {
  'host_name': 'compute1.host.com',
  'service': 'compute',
  'zone': 'nova'
 },
 {
  'host_name': 'compute2.host.com',
  'service': 'compute',
  'zone': 'nova'
 },
 {
  'host_name': 'sched1.host.com',
  'service': 'scheduler',
  'zone': 'internal'
 },
 {
  'host_name': 'sched2.host.com',
  'service': 'scheduler',
  'zone': 'internal'
 },
 {
  'host_name': 'vol1.host.com',
  'service': 'volume',
  'zone': 'internal'
 }]
}
