[Crash-utility] cacheutils extension module update

Hi Dave, I've enhanced my cacheutils extension module, and now it has three commands "ccat", "cls" and "cfind". https://github.com/k-hagio/crash-cacheutils Could you please update the command help pages in your extensions page? Main changes: - Add a new "ccat -d" option that extracts a directory and its contents with one command: crash> ccat -d /var/log /tmp/log Extracting /var/log to /tmp/log... done. - Add a new "cfind" command that can be used to search for files through a specific directory or the whole file system: crash> cfind / | grep messages ffff88010113be00 /var/log/messages ffff880449f86b40 /usr/lib/python2.7/site-packages/babel/messages - Add a new "cfind -c" option that counts the number of directory entries in a directory and its subdirectories: crash> cfind -c /boot TOTAL DENTRY N_DENT PATH 18 12 6 /boot 8 6 2 /boot/grub2 34 34 0 /boot/grub2/locale 268 268 0 /boot/grub2/i386-pc 1 1 0 /boot/grub2/fonts 1 1 0 /boot/efi 2 1 1 /boot/efi/EFI 3 0 3 /boot/efi/EFI/redhat 335 323 12 TOTAL - Add a new "-n" option to each command to support mount namespaces. Thanks, Kazu
