Feature request: Be able to send specific fields to hipchat

Description

Instead of sending the entire log message, we should be able to send only specified fields.

For example, in the grok section we extracted out field1, field2, field3
In the output section, we should be able to do

hipchat {
color => "x"
room_id => "x"
token => "x"
message => "Event A has happened: %{field1},%{field2}, %{field3}"
}

This ability will clean up the output to show only the most critical information. For long very verbose logs, this is a must.
