Title:
  trusted_filter cache does not work

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  The cache in trusted_filter does not work because a new instance of
  TrustedFilter is made each time, which creates it's own cache.

  This means that each time a new instance is scheduled, the
  TrustedFilter will query the attestation service for all hosts - which
  is a very slow operation.
