local-config element doesn't work with ironic-agent

[Ramakrishnan G (rameshg87)]

Currently I can create an ironic-agent ramdisk from dib using the command:
/opt/stack/diskimage-builder/bin/disk-image-create -a amd64 -o agent-ramdisk fedora ironic-agent disable-selinux

I can add the local-config element to copy the ssh keys to the ramdisk (ironic-agent has an ssh service running). But adding local-config doesn't copy the ssh keys.

    Selectively prune /root for ironic-agent ramdisk

    Previously all files in /root were ignored when building the
    ironic-agent ramdisk. This prevented for example to use the
    local-config element to connect to the ramdisk via ssh as root user.

    This commit change the exclude rule on /root to only ignore the
    /root/.cache directory.
