求助: UI界面设置host参数无效

[yi-guo-546]

Describe the bug
运行了example的http文件，发现无法通过master UI界面设置的host参数传递到url生效，请问该如何设置呢

Expected behavior
8089 UI界面可以设置host参数传递到url

Environment (please complete the following information):
boomer: master分支

后续可以考虑像 locust 一样，用一个 environment 全局变量存一下 master 发过来的各种参数，供用户在编写 task 的时候，自行去读。

I also need this feature!

When the host url is set in master UI, that value is passed to boomer by the host field in spawn message.
I’ve tried to implement a workaround for this by adding an event handler for spawn.

@ikorihn I think you can submit a PR.
