[rhel7-branch][PATCH] Add tmpfs support

[Martin Kolman]

This makes it possible to create arbitrary tmpfs mounts
using the kickstart part command, for example:
part /tmp --fstype=tmpfs --size=700
part /foo --fstype=tmpfs --maxsize=500 --grow

And as --size only supports integers,
explicit size in % of RAM can be set like this:
part /bar --fstype=tmpfs --fsoptions="size=25%"

So far this works with kickstart,
custom partitioning seems to have some
issues with it and I'm investigating them.
