cli: Add clean and status subcommands

The 'cloud-init clean' command allows a user or script to clear cloud-init
artifacts from the system so that cloud-init sees the system as
unconfigured upon reboot. Optional parameters can be provided to remove
cloud-init logs and reboot after clean.

The 'cloud-init status' command allows the user or script to check whether
cloud-init has finished all configuration stages and whether errors
occurred. An optional --wait argument will poll on a 0.25 second interval
until cloud-init configuration is complete. The benefit here is scripts
can block on cloud-init completion before performing post-config tasks.
