* chore: fix some errors detected by staticcheck
* feat: remove `rand.Seed()` usage for possibly using "fastrand64" runtime to avoid locking
ref: https://pkg.go.dev/math/rand#Seed
* 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

Issue #2605 brought up real problem that QUIC dialer doesn't support sockopt at the moment. Inside `internet.DialSystem(...)` function, one of the branch that involves `redirect(...)` returns `cnc.connection` instance that is currently unhandled by the code logic, and thus caused program panic during runtime.
It seems the sockopt support for QUIC protocol requires a couple changes including making `cnc.connection` public, such that we can handle in dialer, along with some thorough tests, this commit simply adds safety check to explicity state the fact that QUIC isn't working with sockopt. And the implementation of the feature can be scheduled later on.
* Added tcp fragmentation for freedom outbound
* Added TCP_NODELAY to outbound sockopt
* Changed fragment parameters to accept ranges and changed strategy to use length
* Changed packetNumber to packets, supporting range.
* Refactored the freedom fragment logic
* Refine Write()
