IMPALA-3490: Add flag to reduce minidump size

IMPALA-2686 added the breakpad library to all impala daemons, thus enabling them
to write minidump files. This change introduces a flag
'minidump_size_limit_hint_kb', which causes breakpad to reduce the amount of
thread stack memory it includes in a minidump, aiming to reduce the minidump
size during crashes with a lot of threads. Once a minidump is expected to
exceed the configured value, breakpad will include the full stack memory for the
first 20 threads, and afterwards capture only 2KB of stack memory for each
additional thread.
