Juro Bystricky 2395f6bf3e python-probe.c: remove python probe
Remove all references to python probe. The python exceptions
are handled entirely in Python code. This telemetrics-client
package does not need to be aware of the Python code exception handling
and does not need to make any provisions for it (such as creating
services and directories).
It is the responsibility of Python exception handling to properly
interface with the telemetry library.

Tian Baofeng bc7e2610ee pstore_probe.c: add ramoops file support in pstore probe for cl telemetry
Add support for ramoops files in pstore probe, get the crash information
from "/sys/fs/pstore/dmesg-ramoops-x" files.
Add the "-f" cmd option support to input runtime config file when
running the probe.
