Description of the bug

We are seeing some test failures on master branch since the following kdump remote feature PRs were merged.

sonic-net/sonic-host-services#166
sonic-net/sonic-utilities#3400

These are seen during test cases which run config reload on kvm testbeds and is blocking many PRs on sonic-buildimage.
