Support for customizing haproxy template #20
Description
A lot of applications needs to customize the default settings for haproxy. It would be impossible to get all the settings into etcd. We should have a way to customize the default haproxy template , without a need to clone the repository.
There is an existing logic, that fetches certs from Amazon S3. We can update the logic to also fetch haproxy template from S3 if it exists, else it can use the default template from container.
