Missing /var/snap/subutai/common/lxc/ in 6.3.1

[happyaron]

In a fresh installation of Ubuntu 16.04.3 RH, /var/snap/subutai/common/lxc/ does not exist, so that management container cannot be imported:

Creating the tmpdir manually can work around it:
mkdir -p /snap/subutai/common/lxc/tmpdir

For proper manual installation of snap one should consult this doco: https://github.com/subutai-io/snap/wiki/Installation-of-Subutai-snap-package

Specifically it is mentioned there:
Initialization of BTRFS storage volume for Subutai

The appropriate partition (or disk), say /dev/sdb, should be present prior to running the btrfsinit script

Otherwise, one could benefit from using either one of our Vagrant boxes or autobuild.sh script

Creating the tmpdir manually can work around it:
mkdir -p /snap/subutai/common/lxc/tmpdir

This is not a good solution for fresh installs since BTRFS won't be inited in this case
This works for already existing peers where for some reason the aforementioned folder is missing
