Number of cores generated per process exceeds max limit

[Sundaresan Rajangam]

Number of cores generated per process should not exceed the max limit of 4 [limit set in nodemgr]

nodemgr failed to delete the old core file due to incomplete path passed to remove() call to delete the core file

Number of cores generated per process exceeds max limit

nodemgr failed to delete the old core file when the max number of cores
per process exceeded due to incomplete path passed to remove() call.
Fix update_process_core_file_list() which sends core file list without
complete path.
Handle the case when nodemgr doesn't run when the process generates
coredump and exceeds the max limit.
