BUILD: makefile: add a "USE_PROMEX" variable to ease building prometheus-exporter

Browse Source 
The Prometheus exporter has gained in popularity and deserves to be easier
to build. Let's add a standard "USE_PROMEX" variable to enable it without
having to modify EXTRA_OBJS nor fiddling with the build path. The readme
was updated to reflect this.

However, PROMEX is not built by default with HAProxy. It is provided as an extra
component for everyone want to use it. So you need to explicitly build HAProxy
with the PROMEX service, using the Makefile variable "EXTRA_OBJS". For instance:
with the PROMEX service, setting the Makefile variable "USE_PROMEX" to "1". For
instance:
> make TARGET=linux-glibc EXTRA_OBJS="contrib/prometheus-exporter/service-prometheus.o"
> make TARGET=linux-glibc USE_PROMEX=1
if HAProxy provides the PROMEX service, the following build option will be
reported by the command "haproxy -vv":
