Ensure that Boot applications built with Maven use the `-parameters` compiler flag by default

[bclozel]

In #9297 we're considering adding jackson modules to our web starter. One of those modules, the parameter-names one, is only useful if the JDK compiler has the -parameters option set.

This issue is about checking the various places where this option should be set.

So the best we can do now MCOMPILER-298 is fixed is wait for the next release of the maven-compiler-plugin and add the parameters flag to it.

This is super nice when combined with Jackson Java 8 support.

For now, this works:

<plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-compiler-plugin</artifactId>
	<configuration>
		<compilerArgument>-parameters</compilerArgument>
	</configuration>
</plugin>
