On chrome os devices, size of user data directory is limited. We are currently and will deliver large components (100MB ~ GBs). Thus install/update failures caused by insufficient disk space is no longer a corner-case.

Currently in component updater, insufficient space is caught by update_client::InstallError::MOVE_FILES_ERROR. However this error is only reported and processed inside update_client.

Proposal: plumb this error back into cros_component_installer.
