Create Sonar Plugin - Constant string values used in development

 There are few String constants used in Sonar Plugin creation. It's always better to have all these in a one single place.

package com.plugin.sonar.util;

public final class FooConstants {

    private FooConstants() {
    }

    public static final String LANGUAGE_KEY = "foo";
    public static final String LANGUAGE_NAME = "Foo";

    public static final String FILE_SUFFIXES_KEY = "sonar.lang.patterns.foo";

    public static final String JSON_PROFILE_PATH = "foo_quality_profile.json";

    public static final String PATH_TO_RULES_XML = "/foo-sonar-rules.xml";

    public static final String RULES_KEY = "foo";
    public static final String REPO_KEY = LANGUAGE_KEY + "-" + RULES_KEY;
    public static final String RULES_NAME = "Foo";
    public static final String REPO_NAME = LANGUAGE_KEY + "-" + RULES_NAME;
    /**
     * {@code Extractor} related constant values
     */
    public static final String FooSQL_JAR = "/foo-rule-engine.jar";

    public static final String RULES = "/Rules.xml";

    /**
