For some use cases, it can be useful to keep all the kernels
and not just keep the latest one. Add a parameter that allows
it, and continue cleaning up kernels by default.

As described in the comment, there is a dnf equivalent of this command
that doesn't require us installing yum-utils (which drags in yum on
dnf-only systems such as f23)
This is a small consequence to this -- due to us not installing
yum-utils some installs will now be completely yum free. This causes
a breakage in ironic-agent 99-remove-extra-packages where we remove
the yum package. There is a long-standing bug/feature where missing
packages in a group of packages do not cause yum/dnf to exit with
failure, but uninstalling a single package will. Because we have made
the systems yum-free, the uninstall of yum can fail in this corner
case.
It has always been like this, so I'm in favour of the "ain't broke"
approach. To work-around this, I have just put yum into the existing
list of packages to be cleaned up. I have added a note to the yum
installer taking note of this behaviour for future reference.

dib-run-parts filters the acceptable characters in script names,
and "." is not allowed (see $allowed_regex there), so
01-clean-old-kernels.sh is never executed.
Rename it to drop its .sh extension, so it is executed for real.
