* Add UserFunctionCache to cache UDF's library This patch replace LibCache with UserFunctionCache. LibCache use HDFS URL to identify a UDF's Library, and when BE process restart all of downloaded library should be loaded another time. We use function id corresponding to a library, and when process restart, all downloaded libraries can be loaded without another downloading. * update
