Add support for disabling certificate validation in Spring Boot Admin

[TimHess]

In order to work around certificate trust issues, particularly of the ASP.NET Core dev certs, it would be nice to be able to turn off certificate validation in Spring Boot Admin. There is no built-in feature, so it looks like it'll take custom code

Aspire goes a step further by mounting the ASP.NET dev cert in the docker container.
