Subject: [PATCH] Container env SERVER_PASS -> proxy_pass line

Adds a container env variable `SERVER_PASS`
to replace the `proxy_pass` line
e.g.
```
SERVER_PASS='proxy_pass http://container_name:8080'
SERVER_PASS='fastcgi_pass fastcgi://container_name:8080'
SERVER_PASS='grpc_pass grpc://container_name:8080'
```
Note: This is not using upstream_name
