The 'hirsute' key in c-h/core/host_factory/ubuntu.py: UBUNTU_RELEASES had been missed out, and is needed for hirsute support in many of the charms. This sync is to add just that key. See also [1] Note that this sync is only for classic charms. [1] https://github.com/juju/charm-helpers/pull/598 Change-Id: I28452434a99bdd317eecaad65c49759605fa6e21
