[Bug 1848102] [NEW] ZFS Installer create ZVOL for swap

[Michael Ralston]

Public bug reported:

I've been experiencing problems with a system installed via the new
Ubiquity ZFS installer.

When the system gets low on memory, it starts doing heavy IO (to my SSD
in this case), and the system freezes for several minutes.

My system has 16gig of ram, arc cache uses roughly 4gig of that when the
system freezes. Just need to have phpstorm, intellij and chrome open to
put enough memory pressure to make it freeze.

I'm reporting this bug here as I believe the Ubiquity ZFS Installer
should create a swap partition instead of making it a ZVOL.
