both setup snapd and install snaps.
.. note::
Both ``assertions`` and ``commands`` values can be either a
dictionary or a list. If these configs are provided as a
dictionary, the keys are only used to order the execution of the
assertions or commands and the dictionary is merged with any
vendor-data snap configuration provided. If a list is provided by
the user instead of a dict, any vendor-data snap configuration is
ignored.
The ``assertions`` configuration option is a dictionary or list of
properly-signed snap assertions which will run before any snap
``commands``. They will be added to snapd's assertion database by
invoking ``snap ack <aggregate_assertion_file>``.
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If 'side-loading' private/unpublished snaps on an instance, it is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.
**Development only**: The ``squashfuse_in_container`` boolean can be
set true to install squashfuse package when in a container to enable
snap installs. Default is false.

Import assertions by concatenating each assertion into a
string separated by a '

then invoke `snap ack /path/to/file` and check for errors.
If snap exits 0, then all assertions are imported.
