Minor improvements

Hello Snapcrafters! The Snapcraft team is pleased to announce that version 3.5.1 is out.
This is a minor point release to fix some outstanding issues.

New in this release

Core

Legacy re-execution CLI

The CLI logic has been reworked in a way that re-execution into the legacy code base is only done for the build commands. This enables users of snapcraft with projects that have not migrated to bases to use the newer versions of the store commands.

Warnings when not using bases and links to upgrade paths are also presented now.

Destructive Mode

The clean command is now enabled with --destructive-mode.
