cc_snap: Add new module to install and configure snapd and snap packages.

Support installing and configuring snaps on ubuntu systems. Now,
cloud-config files can provide a list or dictionary of snap:assertions
which will be allow configuration of snapd on a system via 'snap ack'
calls. The snap:commands configuration option supports arbitrary system
commands intended to interact with snappy's cli. This allows users to run
arbitrary snappy commands to create users, download, install and
configure snap packages and snapd.

This branch also deprecates old snappy and snap_config modules leaving
warnings in documentation and runtime for consumers of these modules.
Deprecated snap* modules will be dropped in cloud-init v.18.2 release.
