write xmlrpc function getProdCompInfo that is to be contributed to the upstream. Please refer to the following url for details on Bugzilla::RPC 2.18 functions mapped to upstream Bugzilla::WebService and for 2.18 xmlrpc functions sorted by percentage of calls: https://engineering.redhat.com/trac/bugzilla-3.0-rh/wiki/XmlrpcCrossComparison#a2.18xmlrpcfunctionssortedbypercentageofcalls
Please see: https://bugzilla.redhat.com/show_bug.cgi?id=427904#c1 I think that this function should be deleted.
This function also will not be ported to compat_xmlrpc temporary API as it is not highly used and also its functionality will be accomplished in the new WebService API Bugzilla::WebService::Component Noura
