Quieten output from native-image-plugin

[wilkinsona]

Even when running a single smoke test, native-image-plugin outputs five lines per smoke test:

> Configure project :actuator-webflux
[native-image-plugin] Instrumenting task with the native-image-agent: bootRun
[native-image-plugin] Instrumenting task with the native-image-agent: generateAotSources
[native-image-plugin] Instrumenting task with the native-image-agent: jvmAotTest
[native-image-plugin] Instrumenting task with the native-image-agent: nativeAotTest
[native-image-plugin] Instrumenting task with the native-image-agent: test

> Configure project :actuator-webmvc
[native-image-plugin] Instrumenting task with the native-image-agent: bootRun
[native-image-plugin] Instrumenting task with the native-image-agent: generateAotSources
[native-image-plugin] Instrumenting task with the native-image-agent: jvmAotTest
[native-image-plugin] Instrumenting task with the native-image-agent: nativeAotTest
[native-image-plugin] Instrumenting task with the native-image-agent: test

> Configure project :aspect
[native-image-plugin] Instrumenting task with the native-image-agent: bootRun
[native-image-plugin] Instrumenting task with the native-image-agent: generateAotSources
[native-image-plugin] Instrumenting task with the native-image-agent: jvmAotTest
…

It would be nice to silence this output if we can.

This is due to some task creation that's happening at configuration time. If we defer that creation until execution time, the output is only produced for the smoke test that's being run.

I think we can go a step further. There's a predicate that we can configure to control which tasks are instrumented with the native image agent. I think we can safely turn it off completely.
