As a GeoServer Administrator,
I need to avoid the GeoServer Wicket UI full lock when updating/writing the configuration.
It would be nice to show a "Server Busy" page only on the sections capable of modifying the configuration to other users while having the possibility of browse read-only ones instead. The user who launched the configuration update operation should be able to continue browsing all the pages in order to intervene by stopping or deleting the request if needed.
The requisites are:
1. If USER-A launches a catalog write operation, the Wicket UI should not be locked for him.
2. If USER-A launched a catalog write operation, the wicket UI should redirect to a "Server Busy" page any other USER-X only for write-enable sections, while the read-only ones will continue working as usual.
