This is an attempt to stabilize the tests. They are currently flaky
due to a timeout that appears to occur because the mock web server isn't
responding quickly enough. A larger timeout will either confirm this if
the tests stabilize or indicate that the problem has a different cause
if they do not stabilize.

Using a single scrape attempt that is protected by Awaitility should
protect against instability of the OpenTelemetry Collector instance
running in the container and will hopefully stabilize the test.
This commit has also increased the timeout for a successful response
to 30 seconds and removed the configuration of the configuration of
the polling delay and interval as the values being set were the same
as the defaults.

Switch nohttp checks to a convention that is applied per-project rather
than at the root. This should help to reduce memory consumption.

When spring-boot-gradle-plugin is using GradleRunner, it needs to be
configured with a custom plugin classpath to account for the fact
that our Gradle plugin is on the classpath of the system classloader
but some of the other plugins would only be available on a
Gradle-created classloader. This imbalance cause class loading
problems as code in spring-boot-gradle-plugin can't see types at
runtime that are only available on the Gradle-created classloader.
To overcome this, we need to configure the GradleRunner with a custom
plugin classpath that contains both spring-boot-gradle-plugin and all
of the other plugins that are used in its various integration tests.
Previously, this was done in GradleBuild that's used by both
spring-boot-gradle-plugin and spring-boot-image-tests. This caused
a problem as spring-boot-image-tests does not have the
above-described problem and trying to correct it did not work leaving
tests that use spring-boot-gradle-plugin unable to see other plugins
such that the native image plugin.
This commit reworks the customization of the plugin classpath so that
it's only done in spring-boot-gradle-plugin's integration tests.
Closes gh-42338
