Title: add flexible configuration through node attributes

you would use this to specify configurations through chef that are not
currently achievable through chef configuration, for example, in a role:

default_attributes(
"datadog" => {
"conf_lines" => {
"memcache_instance_1" => "localhost:1234:my_tag"
}
}
)

Caveat emptor: this makes it possible to specify invalid, possibly unparseable configuration.
