zhipengl 6db227d7c9 Refactor patches for haproxy package.
Use haproxy-config package to package script and service file for
haproxy package.
Create patches sub-folder and move patches file from haproxy/haproxy
folder to this sub-folder.
Refactor haproxy-service-file.patch &
haproxy-spec-add-init-script.patch
as we use haproxy-config to package related files.
Merged meta_add_support_for_tpm.patch &
spec-add-haproxy-env-var-patch.patch
to spec-include-TiS-changes.patch
(renamed from spec-include-TiS-config.patch) as they just includes
adding source code patches.

Deployment test and ping test between VMs pass
config and script files check pass.
