Avoid using sed to render config file

[stonezdj]

There are lots of sed command to render config file, these commands will cause problem when reconfigure because these operation can not be revert

For example in pre-start.erb

sed -i "s|/data/registry:/storage|$mount_point:/storage|" ${HARBOR_PACKAGE_DIR}/docker-compose.yml
When switch from nfs to local, it is still in docker-compose.yml.

The workaround for this issue is to edit the config file and change back to the original version manually.

In the future, these config files should be rendered with template file.
