/**
 * Function which takes a resource address and replaces specific values with "*". Applied to addresses from the r-r-d result
 * before they are {@linkplain ResourceDescriptionRegistry#add(ResourceAddress, ResourceDescription, boolean)} added} to the
 * resource description registry.
 * 
 * The following parts of a resource address are modified by this function:
 * 

 * {@code host} (only if segments > 1)
 * {@code server-group}
 * {@code server} (if it's the 2nd segment of the address)
 * {@code server-config} (if it's the 2nd segment of the address)
 * 
 * 
 * Examples:
 *
 * 
 * /host=primary/server-config=server-one → /host=*/server-config=*
 * /host=primary/server=server-one/subsystem=data-sources → /host=*/server=*/subsystem=data-sources
 * /server-group=main-server-group → /server-group=*
 * /subsystem=mail/mail-session=foo/server=bar → /subsystem=mail/mail-session=foo/server=bar
 *
