Multiple scoped roles on topology presenter

Currently the topoogy presenter is using the following @AccessControl annotation:

@AccessControl(resources = {
    "/server-group={addressable.group}",
    "/{selected.host}/server-config=*"
    }, recursive = false)

This has a number of drawbacks:

• When the user is assigned to several server-group scoped roles (all of them addressable), only the first addressable group is taken into account when the security context is created.
• The wildcard for server-config does not result in exact operation permissions for the distinct servers.

To address these issues, the topology presenter should create a security context using the resources from the current topology. Thus the presenter would first read the topology and then use this information to create a security context with addresses for the server-groups, hosts and servers.
