Retracted: Phantom module path. The Go proxy cached this as a separate module.
Every version is retracted so 'go install go-micro.dev/v5/Debug@latest' errors or
resolves to the next non-retracted version instead of this path.
TCPCheck will tell the service provider to check the service address
and port every `t` interval. It will enabled only if `t` is greater than 0.
See `TCP + Interval` for more information [1].
