IMPALA-7508: Add Impala Python GDB module
This patch adds a new Impala Python GDB module, and implements
a couple of covenience commands to make core dump analysis
easier.
The initial commands let us find queries and fragment instances
currently executing in an impalad at the time the daemon crashed:
(gdb) source impala-gdb.py
(gdb) find-query-ids

364525e12495932b:73f5dd0200000000
bc4a3eec25481981:edda04b800000000
(gdb) find-fragment-instances
Fragment Instance Id Thread IDs
364525e12495932b:73f5dd02000000a2 [69]
364525e12495932b:73f5dd0200000171 [196, 136]
bc4a3eec25481981:edda04b8000001a8 [252, 237, 206]
f74c863dff66a34d:1d983cc30000009b [200, 14, 13, 12, 6, 5, 3, 2]
f74c863dff66a34d:1d983cc30000013a [4]
The commands have only been tested with Impala 2.12, and are not
expected to work with older versions since it uses ThreadDebugInfo
stuff from IMPALA-6416.
It is hoped that people contribute more commands to the module.
