Microprofile Rest Client's AsyncInvocationInterceptor has wrong lifecycle

[pdudits]

AsyncInvocationInterceptors should intercept single asynchronous invocation with following lifecycle:

• new interceptor is created for every async invocation
• prepareContext() is invoked just before the invocation leaves the main thread
• applyContext() is invoked on executing thread before invocation proceeds
• removeContext() is invoked on executing thread after invocation finishes

Current lifecycle is as follows

• one interceptor per client instance is created
• prepareContext() is invoked at the time of creation

The other methods are invoked as above. Effectively it means, that any interceptors have correct context only at first use, and only if client is already created in correct context (i. e. not on startup).

I might have capacity to provide a PR next month

@pdudits Thank you for this find. I have totally missed this behavior.
