If the context contains three keys:
[{'keystone': {...}, 'db': {...}, 'keystone_master_region': '...'}]

the charm fails to generate the novarc.

change this to
    if len(context.keys()) >= 2:

Actually, this should be:

    if len(context.keys()) == 3:

all three of these keys should be present.

if you want to be MORE specific about which keys this should be:

if (set(context.keys()) == {"keystone", "db", "keystone_master_region"})
