Bharath Vissapragada ce09269fde IMPALA-6747: Automate diagnostics collection. ...

This commit adds the necessary tooling to automate diagnostics
collection for Impala daemons. Following diagnostics are supported.

1. Native core dump (+ shared libs)
2. GDB/Java thread dump (pstack + jstack)
3. Java heap dump (jmap)
4. Minidumps (using breakpad) *
5. Profiles

Given the required inputs, the script outputs a zip compressed
impala diagnostic bundle with all the diagnostics collected.

The script can be run manually with the following command.

python collect_diagnostics.py --help

Tested with python 2.6 and later.

* minidumps collected here correspond to the state of the Impala
process at the time this script is triggered. This is different
from collect_minidumps.py which archives the entire minidump
directory.
