xenapi: boot from volume without image_ref

Currently xenapi does not deal well with image_meta that does not
contain "disk_format". This happens when we get image_meta from an
associated volume, rather than from glance.

Skip central agent interval_task when keystone fails

There is a chance when ceilometer-agent-central try to trigger interval_task
but keystone is not available, then an exception is raised but not caught, the
outside oslo.loopingcall will stop calling the task function, finally leading
to the agent-central service is no longer available forever, even the keystone
is available again.

We can skip the particular interval_task when keystone is not available.
