This is another pre-requisite work for upcoming decompression filter. In this patch we implement the "filter-sequence" directive which can be used in proxy section (frontend,backend,listen) and takes 2 parameters The first one is the direction (request or response), the second one is a comma separated list of filter names previously declared on the proxy using the "filter" keyword. The main goal of this directive is to be able to instruct haproxy in which order the filters should be executed on request and response paths, especially if the ordering between request and response handling must differ, and without relying on the filter declaration ordering (within the proxy) which is used by default by haproxy. Another benefit of this feature is that it becomes possible to "ignore" a previously declared filter on the proxy. Indeed, when filter-sequence is defined for a given direction (request/response), then it will be used over the implicit filter ordering, but if a filter which was previously declared is not specified in the related filter-sequence, it will not be executed on purpose. This can be used as a way to temporarily disable a filter without completely removing its configuration. Documentation was updated (check examples for more info)
