While we have the guard rails for good reason, a user on the shell
should be able to override them and create partitions as they see fit,
e.g. if they have a MBR they don't care about anyway, it should still
be possible to force create a new fixed partition that overlaps it
and pass that to Fastboot for example.
Let's add a new -f (force) parameter that enables this.
