kdump plugin does not check available disk space

[bjking1]

The kdump plugin for ServiceReport currently flags no problems, even if the target filesystem that kdump will write to is undersized or has insufficient free space to save a dump. For example, I have an LPAR with 62TB of memory with a 34GB root filesystem, with only 2GB left free space, and ServiceReport does not flag this as a problem. I think this would be a useful enhancement, particularly for users with large amounts of RAM, as the default filesystem size is likely to be too small in these cases.

Nice suggestion @bjking1

We will add a new check in both kdump and fadump plugin to raise a red flag if dump target does not have sufficient space.
