The set-health command is called from within a snap to inform the system of the
snap's overall health.

It can be called from any hook, and even from the apps themselves. A snap can
optionally provide a 'check-health' hook to better manage these calls, which is
then called periodically and with increased frequency while the snap is
"unhealthy". Any health regression will issue a warning to the user.

Note: the health is of the snap only, not of the apps it contains; it’s up to
the snap developer to determine how the health of the individual apps is
reflected in the overall health of the snap.

status can be one of:

- okay: the snap is healthy. This status takes no message and no code.

- waiting: a resource needed by the snap (e.g. a device, network, or service) is
not ready and the user will need to wait. The message must explain what
resource is being waited for.

- blocked: something needs doing to unblock the snap (e.g. a service needs to be
configured); the message must be sufficient to point the user in the right
direction.

- error: something is broken; the message must explain what.
