A few config options, namely: skip_cpu_compare_at_startup,
skip_cpu_compare_on_dest, nagios_context, and nagios_servicegroups, use
underscores instead of following the convention of using dashes. This
commit fixes skip_cpu_compare_* to skip-cpu-compare-* to ensure
conformance with the precedent since they are new options to the charm
and can be modified safely.
