MINOR: http-rules: Add set-pathq and replace-pathq actions

MINOR: http-rules: Add set-pathq and replace-pathq actions

These actions do the same as corresponding "-path" versions except the
query-string is included to the manipulated request path. This means set-pathq
action replaces the path and the query-string and replace-pathq action matches
and replace the path including the query-string.

This patch may be backported to 2.2.
