Some useful feign extensions
Writes logs in format:
DEBUG feign.Logger - http req-id=[701d8882-e43b-4af3-b5e5-7dc4b4cf4de7] call=[someMethod()] method=[GET] uri=[http://api.example.com]
DEBUG feign.Logger - http req-id=[701d8882-e43b-4af3-b5e5-7dc4b4cf4de7] status=[200] reason=[OK] elapsed-ms=[273] length=[0]
Then you can grep such logs with | cut -f 3 (with right column number)
Also this logger adds unique req-id string to merge request and response.
All retries and error log lines have such string too.
This string is changed each request.
