[IMPALA-3509] Breakpad minidumps can be very large when the thread count is high, e.g., because of many sender threads in large clusters / many fragments

Description

The size of minidump files is proportional to the number of running threads at the time of a process crash. In scenarios when the thread count is high, e.g., because of many sender threads in large clusters / many fragments, we could write very large files. As a countermeasure for those cases, writing minidump files can be disabled by setting the -minidump_path= flag to an empty value.
