    Catch missing Glance image attrs with None

    Glance is known to drop values from its response if they don't resolve to true.
     Previously in I67b7dd16a94fe60d873c012f6bd246ab24500d5a the None catch was
     removed as this WILL cause a call to glance for missing value and
     optimizations where made to attempt to pre-cache values that can be missing
     in expected ways. However there are still situations that can't be optimized.

    Notably this can occur with disk_format, container_format, name, deleted,
     and checksum.
