Snap ``commands`` is a dictionary or list of individual snap
commands to run on the target system. These commands can be used to
create snap users, install snaps and provide snap configuration.
.. note::
If 'side-loading' private/unpublished snaps on an instance, it is
best to create a snap seed directory and seed.yaml manifest in
**/var/lib/snapd/seed/** which snapd automatically installs on
startup.

a Import list of assertions.
Import assertions by concatenating each assertion into a
string separated by a '
'. Write this string to a instance file and
then invoke `snap ack /path/to/file` and check for errors.
If snap exits 0, then all assertions are imported.
