Allow HAProxy stats to be pinned to one or more processes

Browse Source 
When HAProxy is run in multi-process mode, the single stats page
shows metrics for one of the processes at a time, with a random
selection made on page reload.

Whilst a more complete solution may be to enable a stats page for
each process, this is a little cumbersome. This addition allows
the stats page to be pinned to one process, providing a partial
snapshot of the state of the instance.
