[core] Add support for vsock transport (#32847)
This is another attempt to add support for vsock in grpc since previous PRs(#24551, #21745) all closed without merging. The VSOCK address family facilitates communication between virtual machines and the host they are running on. This patch will introduce new scheme: [vsock:cid:port] to support VSOCK address family. Fixes #32738. --------- Signed-off-by: Yadong Qi <yadong.qi@intel.com> Co-authored-by: AJ Heller <hork@google.com> Co-authored-by: YadongQi <YadongQi@users.noreply.github.com>pull/33277/head
