[Feature Request] Supress checks on startup

[rg9400]

Is your feature request related to a problem? Please describe.
I run Uptime-Kuma in a large compose file with many services. It does not always start first, and it's too complicated to add it as a dependency for every single service. This means that on startup of my host, it notices a lot of containers that have yet to start being down, and then finds them up on the next check, triggering multiple false notifications.

Describe the solution you'd like
An option to suppress the uptime checks on startup of uptime-kuma. Might be helpful to give a configurable amount of time in case it varies by user

Describe alternatives you've considered
Ideally, I would keep uptime-kuma on a separate host so it can actually track when my docker stack is down. However, I still find it useful to find when applications break, so having it within my single stack is useful enough for me.

I can also just live with the false positives on startup

I would suggest putting Uptime-Kuma in a separate compose file. It makes no sense to run the tool in the same compose with services you are monitoring.
