This patch adds 'service_dependecies' action to deployables controller, where user can see diagram of assembly service's dependencies declared in deployable XML. For now it's proof of concept for the feature.
Reviewer needs to install those RPMs: - graphviz - graphviz-ruby - gem ruby-graphviz (will need to be packaged if we want to use this patch. Packaging of it will be good also for DC, where it's used for drawing instance states diagram)
Also I will add tests when community approve this patch.
Reviewer could run into https://bugzilla.redhat.com/show_bug.cgi?id=831201 during reviewing (easy workaround - fix line 196 in deployable.rb with 'audrey_error = nil').
