    Fix pci_alias that include white spaces
    
    When the PCI alias was getting translated to a PCI request,
    all the white spaces were getting removed. So the pci_passthrough:alias
    specified in the flavor never matched the device in pci_alias.
    This patch fixes the bug by only stripping the white spaces
    at the beginning or the end of the elements

Title:
  Failed to boot vm with pci_alias's name including space in nova.conf

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  Description
  ===========
  Failed to boot vm with pci_alias's name including space in nova.conf.

  
  Steps to reproduce
  ==================
  1.modify the key pci_alias, pci_passthrough_whitelist and scheduler_default_filters in /etc/nova/nova.conf
  pci_alias = {"name": "Cirrus Logic", "product_id": "0ff2", "vendor_id": "10de"}
  pci_passthrough_whitelist = [{"product_id": "0ff2", "vendor_id": "10de"}]
  scheduler_default_filters = ...,PciPassthroughFilter

  2.restart nova-api, nova-scheduler, nova-conductor, nova-compute
  serivces

  3.update a flavor's metadata with command
  nova flavor-key  m1.tiny set "pci_passthrough:alias"="Cirrus Logic:1"

  4.create instance with command
  nova boot --flavor m1.tiny --image cirror --nic net-id=xxxxxxxxx vm_name

  
  Expected result
  ===============
  There will be a vm with gpu passthrough.

  
  Actual result
  =============
  Failed to boot vm.
  Error occurs in nova-api.log

  
  Environment
  ===========
  1. Devstack with newton version

  
  Logs
