Each config file can redirect request through an dedicated fcgi server.
It use the first param from the handler to match on ServerName.
If no fcgi config found, use first.

This is just a daft, I'm open to discuss about this implementation

Already tested on 1.6.9, but test needed on master.

Exemple:
server.site:

[HANDLERS]
....
MATCH 
/myfirstapi/* fastcgi foo
/mysecondapi/* fastcgi bar

/etc/monkey/plugins/fastcgi/fastcgi-first.conf

[FASTCGI_SERVER]
    ServerName foo

/etc/monkey/plugins/fastcgi/fastcgi-second.conf

[FASTCGI_SERVER]
    ServerName bar
