支持设置 ServletName 的 CamelHttpTransportServlet
升级到 Grails3 后，没了 web.xml，只能通过 ServletRegistrationBean 来注册 servlet，此时默认的 seveletName 为类名。
此时，如果用原始的 CamelHttpTransportServlet 类来注册 servlet，则名称为 camelHttpTransportServlet；
但是对于 servlet:// 的路由，除非在 url 上加上 servletName = camelHttpTransportServlet，否则会默认注册到名为 CamelServlet 的注册表中，导致路由不生效。
于是，新增子类 CamelServlet 和可接收自定义名称的构造器，并且通过 RoutingGrailsPlugin 设置名称为 CamelServlet。
测试代码：
def s = ctx.camelServlet.servlet
println "servletName == " + s.servletName // 应该是 "CamelServlet"
org.apache.camel.component.servlet.DefaultHttpRegistry.registries.each{
println "============" + it + "n" + it.value.consumers + "n" + it.value.providers
