HAproxy ACL support for map in configuration UI
When defining ACLs with the GUI, it would be nice to have support for matching against a map for "Host matches:" type functions.
That is, I suggest implementing the use of map functions documented here : https://cbonte.github.io/haproxy-dconv/1.7/configuration.html#7.3.1-map
Used in conjunction with Aliases, it would allow for more dynamic and smooth configuration when validating hostnames.
(It might also be nice to have Key-Value type Aliases, which would be usable in the future for selecting a backend based on criteria specified in the map)
