1.3.1 breaks availability monitoring

[agross]

I'm using Uptime Kuma to check for the healthiness and correctness of my notify_push setup. It involves reverse proxies and Redis, and there have been instances where a configuration change broke my setup and the monitor outlined below caught it instantly.

The monitor is a simple HTTP request (using Uptime Kuma, but this is unrelated):

$ curl https://nc.example.com/push/test/remote/1.2.3.4
1.2.3.4

The Uptime Kuma config also verifies 1.2.3.4 is returned.

With notify_push 1.3.1 in place, this request is now guarded by a token:

$ curl https://nc.example.com/push/test/remote/1.2.3.4
Missing request header "token"

I prefer to keep this simplistic but effective test. Uptime Kuma does not support executing arbitrary binaries like the provided test_client.

My suggestion is to add a configuration value that defines the value of a "test-only" token to be passed in the HTTP header.
