Public bug reported:
YAML has native support for boolean values, and YAML has been around
long enough that it's reasonable to expect people to know how to write
it.
We should phase out accepting multiple string values ("yes", "1",
"true", "on" for True; "no", "0", "false", "off" for False) in places
where we do in favour of YAML boolean values.
A proposed implementation plan:
* Start emitting a warning about such values in the string-handling paths of
util.{is_true,is_false} ASAP
* Some time in the future (perhaps in the lead-up to Ubuntu's 22.04 LTS?),
after we have been emitting these warnings for a good long while, switch the
behaviour of new versions of cloud-init[0] to only accept bools
What do we think?
[0] For Ubuntu, specifically, we should also _not_ change the behaviour of
existing releases when we backport these new versions of cloud-init.
