Refactor app service module

[badboy-huaqiao]

what's current issues about app service implement on UI:

• the default app service configuration called app-rule-engine is the default data source of ruleengine, when encryption, xml conversion, compression functions are used, or the setResponseData function is removed, all rules created by ruleengine service will fail.
• there are some bugs when update the configs, such as repeated setting when click refresh consul button on UI.
• the current layout implement is not properly or friendly to user ,such as users don't know what configs they already used.
• Trigger shouldn't be modified on UI, because app svc needs to restart when Trigger is changed, but right now ui doesn't have the ability to restart this service
• Trigger configs push to ExecutionOrder which is a wrong location instead of Trigger on Register center

the Trigger section still needs a little time to be done, so keep this issue opening until that finished
