Add a min-age option for updates.

[distante]

Describe your core improvement

I would like to get notifications of updates depending on an age option I set for each integration/app defaulting to 0.

Current limitations

Currently, I as soon as an update is discovered, it is shown on the UI with just two options, either ignore it or accept it.

Technical benefits

Given the current state of AI and the amount of code that now can be put into custom integrations (like HACS), it is vital to not introduce possible zero day issues. A cold down time is the way external dependencies are handled in software development and we can use the same here.
