Upgrade to lxd 4.0 using SNAP

@Giuseppe1992 have a look at mininet/mininet/provision/playbooks/install-lxd-debian-10.yml in the branch is55. Instead of a symbolic link for lxc/lxd it adds /snap/bin to the PATH for non interactive bash (what Distrinet uses internally). Maybe it fixes the issue you had.

Huum, not yet a generic solution as it assumes that the user shell is Bash.
