This commit creates pre and post hook directories in
debian package. It adds pre and post hook script support
to be executed before and after crash dump collection
respectively. It executes scripts in alphabetical order
from hook directories.
The implementation ensures that any script failure during execution
does not affect the kdump crash dump collection process.
Pre-hook (/etc/kdump/pre-hooks.d/) scripts execute before vmcore
collection.
Post-hook (/etc/kdump/post-hooks.d/) scripts execute after
successful vmcore collection.
Test Plan:
Pass: Trigger crashdump on AIO-SX and verify pre and post
dump scripts are executed
* Verify in absence of scripts and directory, dump is still
created
* Verify if prehook and posthook scripts fail, dump is still
created
* Verify scripts are executed in alphabetical order. Orders
verified with prefix 001, 002 ,010 etc and 1, 2, 10, 3 etc
Pass: Trigger crashdump on standard with storage configuration
and verify pre and post dump scripts are executed
* Verify pre and post scripts executed in controller node
* Verify pre and post scripts executed in compute node
* Verify pre and post scripts executed in storage node
