Title: Ganglia input: Store the value and ganglia name.

Previously, we only had metadata in events, which wasn't very useful. An event would look like
this:

{
"@version" => "1",
"@timestamp" => "2014-09-22T10:51:59.337Z",
"log_host" => "example.com",
"dmax" => 0,
"tmax" => 90,
"slope" => "both",
"type" => "float",
"units" => "%",
"host" => "1.2.3.4"
}

Events now look like this:

{
"@version" => "1",
"@timestamp" => "2014-09-22T10:51:59.337Z",
"log_host" => "example.com",
"val" => 0.0, # added
"dmax" => 0,
"tmax" => 90,
"slope" => "both",
"type" => "float",
"units" => "%",
"name" => "cpu_nice", # added
"host" => "1.2.3.4"
}
