[Hawkular-dev] Revisit resource naming + resource types for Alpha4

Hey, we currently have a pretty ad-hoc resource naming scheme, that involves magic constants like "MI~R" or "AI~R" and also sometimes square brackets '[' and ']', which are even invalid characters (if not escaped) inside a URL [1]. A recent switch from resource naming with [] to one without [] created a bit of a mess, as the metric names still expect the [] and probably other clients that are not part of the github.com/hawkular repositories We need to revisit and fix the resource types (e.g. supply WildFly base data from within the Hawkular server) and the resources using those including names of metric definitions , operation definitions etc in Alpha4 before too much code relies on it. Similar I believe that resource info should not contain the full type information every time - only if explicitly requested. Clients should be able to get the type info by following a link that is supplied in the resource info. On top of that we need to publish how client writers can get the data they need.
