Ability to setup library dependencies for single WAR task

  Description of the bug or enhancement

  Single WAR uses the special class loader for core and web modules. It loads classes only from core jars (like app-core.jar, cuba-core.jar) for a core module and web jars for a web module. Libraries (like optaplanner) is loaded by a standard web container class loader.
  For some specific class loaders, (like OptaPlanner -> Drools classloaders) possible case exists when one class is loaded by different class loaders: core class loader and standard web container class loader. And OptaPlanner doesn't check rules correctly if one class loaded by different class loaders. e.g. a rule that checks class on equality.

There is only one way: optaPlanner library should be loaded using core class loader.

We'll introduce properties coreAdditionalJarNames and webAdditionalJarNames on CubaWarBuilding. You can define jar names that loaded by core or web class loader.

Example:

task buildWar(type: CubaWarBuilding) {
    appProperties = ['cuba.automaticDatabaseUpdate': true]
    webXmlPath = 'modules/web/web/WEB-INF/single-war-web.xml'
    appHome = '../app_home'
    logbackConfigurationFile = 'etc/war-logback.xml'
    includeJdbcDriver = true
    includeContextXml = true
    coreContextXmlPath = 'modules/core/web/META-INF/war-context.xml'
    coreAdditionalJarNames = ['optaplanner-core-7.19.0.Final.jar', 'kie-soup-project-datamodel-commons-7.19.0.Final.jar', 'kie-soup-project-datamodel-api-7.19.0.Final.jar', 'kie-soup-maven-support-7.19.0.Final.jar', 'kie-soup-commons-7.19.0.Final.jar', 'kie-internal-7.19.0.Final.jar', 'kie-api-7.19.0.Final.jar', 'drools-core-7.19.0.Final.jar', 'drools-compiler-7.19.0.Final.jar']
}
