Add default limitation to RestAPI calls which can bring system to not responding. Currently calls like for example:
Search Builds (http://localhost:8810/rest/builds?&lt;search criteria1>=<value1>&<search criteria2>=<value2>&...)
Get child configurations of specified configuration (http://localhost:8810/rest/configurations?parent_id=&lt;parent configuration id>)
Get all descendent configurations of specified configuration (http://localhost:8810/rest/configurations?parent_id=&lt;parent configuration id>&recursive=true)
Get all configurations in the system (http://localhost:8810/rest/configurations?recursive=true)

This kind of RestAPI calls can bring the server in 'not responding' mode, ie UI not accessible at all anymore or heap space problems. It would be good to add some default limit on this calls so that system hang up can be avoided.
