Christopher Faulet 83070a08a2 MEDIUM: promex: Add support for filters on metric names
It is now possible to filter the metrics on their name, by listing
explicitly metrics to dump or on the opposite to exclude only some metrics
from the dump. To do so, a comma-separated list of metrics must be
specified. If a name is preceded by a minus (-), the metric is excluded from
the dump. If at least one metric is specified to be explicitly dumped, all
metrics are no longer dumped, but only those explicitly listed.

The list is specified via one or more "metrics" parameters in the uri
query-string. For insance:

  # Dumped all metrics, except "haproxy_server_check_status"
  /metrics?metrics=-haproxy_server_check_status

  # Only dump frontends, backends and servers status
  /metrics?metrics=haproxy_frontend_status,haproxy_backend_status,haproxy_server_status

Included and Excluded metrics can be mixed. Only the intersection will be
dumped.

This patch should fix the issue #770.

The HAProxy documentation has been split into a number of different files for
ease of use.

Please refer to the following files depending on what you're looking for :

  - INSTALL for instructions on how to build and install HAProxy
  - BRANCHES to understand the project's life cycle and what version to use
  - LICENSE for the project's license
  - CONTRIBUTING for the process to follow to submit contributions

The more detailed documentation is located into the doc/ directory :

  - doc/intro.txt for a quick introduction on HAProxy
  - doc/configuration.txt for the configuration's reference manual
  - doc/lua.txt for the Lua's reference manual
  - doc/SPOE.txt for how to use the SPOE engine
  - doc/network-namespaces.txt for how to use network namespaces under Linux
  - doc/management.txt for the management guide
  - doc/regression-testing.txt for how to use the regression testing suite
  - doc/peers.txt for the peers protocol reference
