Provide mv wrapper task

This task exists as a convenience for users who need predictable sudo
commands without variance to write into their sudoers rules. The only real
variable in commands used by peadm is the filename of the PE installer
tarball. This task can be used in a pre-plan to homogenize calls to sudo.
Rather than literally calling "mv" with a variable filename, the mv.sh task
can be called. Inputs come as environment variables so the call doesn't
change.
