Subject: [PATCH] Fix error caused by increasing proxy_buffer_size (#363)

This fixes the bug raised in #363, by increasing the size of the proxy_buffers (memory allocation) to match the size of the proxy buffer. This leaves the default values (with no ingress setting) unchanged:
```
proxy_buffer_size      4k
proxy_buffers            4 4k
```
If 'proxy-buffer-size' is set, then now both the buffer size and the memory allocation size is increased:
```
proxy_buffer_size     "{{ $location.Proxy.BufferSize }}";
proxy_buffers           4 "{{ $location.Proxy.BufferSize }}";
```
I have been using this patch with 0.8.3 and 0.9.0-beta.2.
