* v5: Health Check & LeastLoad Strategy (rebased from 2c5a71490368500a982018a74a6d519c7e121816) Some changes will be necessary to integrate it into V2Ray * Update proto * parse duration conf with time.Parse() * moving health ping to observatory as a standalone component * moving health ping to observatory as a standalone component: auto generated file * add initialization for health ping * incorporate changes in router implementation * support principle target output * add v4 json support for BurstObservatory & fix balancer reference * update API command * remove cancelled API * return zero length value when observer is not found * remove duplicated targeted dispatch * adjust test with updated structure * bug fix for observer * fix strategy selector * fix strategy least load * Fix ticker usage ticker.Close does not close ticker.C * feat: Replace default Health Ping URL to HTTPS (#1991) * fix selectLeastLoad() returns wrong number of nodes (#2083) * Test: fix leastload strategy unit test * fix(router): panic caused by concurrent map read and write (#2678) * Clean up code --------- Co-authored-by: Jebbs <qjebbs@gmail.com> Co-authored-by: Shelikhoo <xiaokangwang@outlook.com> Co-authored-by: 世界 <i@sekai.icu> Co-authored-by: Bernd Eichelberger <46166740+4-FLOSS-Free-Libre-Open-Source-Software@users.noreply.github.com> Co-authored-by: 秋のかえで <autmaple@protonmail.com> Co-authored-by: Rinka <kujourinka@gmail.com>
