TrustedFilter should not be used if there's no itxt.

Also, the default is: 
                default=[
                  'RetryFilter',
                  'AvailabilityZoneFilter',
                  'RamFilter',
                  'ComputeFilter',
                  'ComputeCapabilitiesFilter',
                  'ImagePropertiesFilter'
                  ]

We should definitely include the same by default.
