   解决issue #571 
   OmegaContext 中使用了 InheritableThreadLocal
   在feign调用开启hystrix时,hystrix会为每个feignClient创建线程池.
   InheritableThreadLocal在第一次创建线程时,可以正确继承到父线程的线程变量,但是当线程被复用时,InheritableThreadLocal不会被更新,导致无法在feign调用的header里传递globalTxId和localTxId
   
   我参考了spring security解决securityContext 线程变量在使用hystrix时,传递线程变量的方案,针对OmegaContext里的线程变量进行了传递,并提供了可扩展的接口
