Code Issues Proposed changes

Improve logs and case-sensitive on k8s-coredump 

Improving logging by adding timestamp and
show error in case we have a KeyError while
trying to verify configurations set by
pod annotations.
Also allowing case-sensitive paths to be
configured as the path to save the coredumps.

PASS: AIO-SX install and bootstrap.
PASS: On a AIO-SX test if k8s-coredump is executed
	successfully.
PASS: On a AIO-DX test if k8s-coredump is executed
        successfully.
PASS: On a Standard test if k8s-coredump is executed
        successfully.
PASS: On a Standard test if k8s-coredump is executed
	successfully using a PVC setup.
