snap_channel cannot be used to change the snap channel post-installation #3

snap_channel is only ever read during the install_packages() handler, which is only called "@when_not('blackbox-exporter.installed')"... which is a flag which never gets unset after initial installation.

This means that, unlike e.g. prometheus-libvirt-exporter-charm, snap_channel is presently only an install-time option; it has no impact if changed after installation has succeeded once.
