Incorrect class loader is used for loading custom Initial context factory in Elytron dir-context

      For reproduction you can use following dir-context:

      <dir-context name="dir-context-localhost" url="ldap://127.0.0.1:10389" principal="uid=admin,ou=system">
    <credential-reference clear-text="secret"/>
    <properties>
        <property name="java.naming.factory.initial" value="com.sun.jndi.ldap.LdapCtxFactory"/>
    </properties>
</dir-context>

      Quoting from [1]:

      DEBUG [org.wildfly.security] (default task-1) Could not create [class javax.naming.ldap.InitialLdapContext]. Failed to connect to LDAP server.: javax.naming.NamingException: WFLYNAM0027: Failed instantiate InitialContextFactory "com.sun.jndi.ldap.LdapCtxFactory" from classloader ModuleClassLoader for Module "deployment.print-roles.war" from Service Module Loader [Root exception is java.lang.ClassNotFoundException: "com.sun.jndi.ldap.LdapCtxFactory" from [Module "deployment.print-roles.war" from Service Module Loader]]

      at org.jboss.as.naming.InitialContext.init(InitialContext.java:101)

      We can see from the stack trace the deployments class loader is being used.

      I think by default the ClassLoader of the subsystem should be used i.e. that will have the common dependencies. However we may want to also add a module attribute so an alternative module can be specified for when creating the InitialDirContext.
