* Configure nest pubsub subscriber automatically
Update the config flow to configure the nest pubsub subscriber automatically.
After completing the authentication step, the user is now asked for the google
cloud console ID, which is needed to create a subscription.
Home Assistant manages the lifecycle of a subscription only when it is created
by the ConfigFlow. Otherwise (if specified in configuration.yaml) it treats
it similarly as before.
These are the considerations or failure modes taken into account:
- Subscription is created with reasonable default values as previously recommended (e.g. retion only keeps 5-15 minutes of backlog messages)
- Subscriptions are created with a naming scheme that makes it clear they came from home assistant, and with a random
string
- Subscriptions are cleaned up when the ConfigEntry is removed. If removal fails, a subscription that is orphaned will
be deleted after 30 days
- If the subscription gets into a bad state or deleted, the user can go through the re-auth flow to re-create it.
- Users can still specifcy a CONF_SUBSCRIBER_ID in the configuration.yaml, and
skip automatic subscriber creation
* Remove unnecessary nest config flow diffs and merge in upstream changes
* Incorporate review feedback into nest subscription config flow
* Update text wording in nest config flow
* Pre-factor nest subscriber to library
Move the nest subscriber to a library that can be reused in a future PR:
- From ConfigFlow for creating subscriptions
- On nest removal to delete subscriptions
This is pulled out of PR #59260 to make that easier to review.
* Resolve pylint error in nest api subscriber
* Remove duplicate constants
