fa89064933
Adds specific disk file classes for EC policy types. The new ECDiskFile and ECDiskFileWriter classes are used by the ECDiskFileManager. ECDiskFileManager is registered with the DiskFileRouter for use with EC_POLICY type policies. Refactors diskfile tests into BaseDiskFileMixin and BaseDiskFileManagerMixin classes which are then extended in subclasses for the legacy replication-type DiskFile* and ECDiskFile* classes. Refactor to prefer use of a policy instance reference over a policy_index int to refer to a policy. Add additional verification to DiskFileManager.get_dev_path to validate the device root with common.constraints.check_dir, even when mount_check is disabled for use in on a virtual swift-all-in-one.
