rewrite DNS plugins

in FD one domain "company.com" could be assign to only one reverse dns "192.168.X.X"

a way to rewrite it could be the following

on server Section when we create a server

• we could choose one or more dns zone ( domain1.com, comain2.com)
• we could choose one or more dns reverse zone ( 10.10.10.X, 15.15.15.X)

on DNS management Section -> reverse dns should managed a by a similar screen as DNS but without MX record -> on both reverse dns and dns management screen , NetworkAddress and netmask should be deleted
