    [SPARK-23644][CORE][UI] Use absolute path for REST call in SHS

    ## What changes were proposed in this pull request?
    
    SHS is using a relative path for the REST API call to get the list of the 
application is a relative path call. In case of the SHS being consumed through 
a proxy, it can be an issue if the path doesn't end with a "/".
    
    Therefore, we should use an absolute path for the REST call as it is done 
for all the other resources.
