Allow disabling external API calls

[PreNoob]

Issue submitter TODO list

• I've searched for an already existing issues here
• I'm running a supported version of the application which is listed here and the feature is not present there

Is your proposal related to a problem?

Currently the start up is delayed by 10 seconds and runs into an io.netty.handler.ssl.SslHandshakeTimeoutException when trying to call api.github.com which fails due to the restriction of external calls from the cluster.

Describe the feature you're interested in

Please provide a configuration parameter that allows disabling all external API calls which should result in not querying the GitHub release info and potential other external API calls in the future.

This could be possible by disabling the instantiation here.

Additional context

I would be open to contributing this feature, if desired.

This can't affect startup time, as it's a non-blocking call and it's not executed upon a start

[PreNoob]

I inferred that it is called at startup from this comment.

Is there any other place api.github.com is called?
My feature request would still be the same.

Thanks, I've followed the call chain from your original message which had no blocking calls.
The new link, however, does that, as a combination of a @Scheduled annotation which will lead to a call performed right after the context initialization, plus a blocking call for a mono gives us exactly that.
