[native] Using setupNativeSidecarPlugin in tests outside presto-native-sidecar-plugin

[pramodsatya]

Helper function setupNativeSidecarPlugin in presto-native-sidecar-plugin/src/test/java/com/facebook/presto/sidecar/NativeSidecarPluginQueryRunnerUtils.java enables user to install the native sidecar plugin on the QueryRunner used for tests. This function is currently only used in the module presto-native-sidecar-plugin; attempting to use this function in a different module (presto-native-tests in this case) results in the following error:

java.lang.NoClassDefFoundError: com/facebook/presto/sidecar/NativeSidecarPlugin
	at com.facebook.presto.sidecar.NativeSidecarPluginQueryRunnerUtils.setupNativeSidecarPlugin(NativeSidecarPluginQueryRunnerUtils.java:24)
	at com.facebook.presto.nativetests.TestRepartitionQueriesWithSmallPages.createQueryRunner(TestRepartitionQueriesWithSmallPages.java:38)
...

Dependency in module's pom.xml (presto-native-tests/pom.xml in this case):

        <dependency>
            <groupId>com.facebook.presto</groupId>
            <artifactId>presto-native-sidecar-plugin</artifactId>
            <version>${project.version}</version>
            <scope>test</scope>
            <type>test-jar</type>
        </dependency>

This error came up while trying to add the native sidecar coordinator plugin to native query runner for running tests in presto-native-tests.
Having a dependency on presto-native-sidecar-plugin with two different scopes, test (to access NativeSidecarPluginQueryRunnerUtils.setupNativeSidecarPlugin) and compile (to access NativeSidecarPlugin), appears to resolve the error. However this change throws an error with maven-checks Github action:

presto % ./mvnw install -B -V -T 1C -DskipTests -Dmaven.javadoc.skip=true --no-transfer-progress -P ci -pl '!presto-test-coverage,!:presto-docs'

...
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:3.1.1:analyze-only (default) on project presto-native-tests: Dependency problems found -> [Help 1]

Not sure if this is the right fix, or whether the function setupNativeSidecarPlugin needs to be modified. Opening this issue to discuss a potential fix for this error.
