Tao Liu 7f3827f24d Keystone token and resource caching
Add the following misc. changes to dcorch and dcmanager components:
- Cache the master resource in dcorch audit
- Consolidate the openstack drivers to common module, combine the
  dcmanager and dcorch sysinv client. (Note: the sdk driver that
  used by nova, neutron and cinder will be cleaned as part of
  story 2006588).
- Update the common sdk driver:
  . in order to avoid creating new keystone client multiple times
  . to add a option for caching region clients, in addition to the
    keystone client
  . finally, to randomize the token early renewal duration
- Change subcloud audit manager, patch audit manager,
  and sw update manager to:
  utilize the sdk driver which caches the keystone client and token

Test cases:
1. Manage/unmanage subclouds
2. Platform resources sync and audit
3. Verify the keystone token is cached until the token is
   expired
4. Add/delete subclouds
5. Managed subcloud goes offline/online (power off/on)
6. Managed subcloud goes offline/online (delete/add a static route)
7. Apply a patch to all subclouds via patch Orchestration
