installing large snaps consumes a load of space in /tmp

[Colin Ian King]

I was experimenting with a fairly large binary snap install and noticed /tmp was filling up, one with a multipart file and another snapd-sideload-pkg file:

-rw------- 1 root root 8589942784 Sep 17 15:02 multipart-032184110
-rw------- 1 root root 3910729728 Sep 17 15:03 snapd-sideload-pkg-351053493

.. the above is a listing during the install of the snap.

the snap install probably should check that there is enough space in /tmp before filling it completely up. I guess nobody has tried this out with large snaps yet to hit this.

I know my above example is a pathologically large snap, but I am concerned that so much space is used when performing the install.
