Confirm if we should use library for apt operations

[Tom Haddon]

Some charms do the following:

`from charms.operator_libs_linux.v0 import apt`

We should confirm if this is the recommended approach and if so implement, bearing in mind how we'd update these libraries as part of charm publishing workflow.

See https://github.com/canonical/mongodb-operator/blob/main/src/charm.py#L267 for an example.

Looking at the current SDK docs, there's a new section (at least to me) about libraries [0].

There is an entry for apt, which points to this "charm" [1][2] that is essentially a collection of libraries. The code from that mongodb charm link seems to come from there.

As it's included in the official documentation, it seems to be the official library for this.

I've released revision 17 to the edge channel which should address this. Since that's now in the upstream code, I'm going to mark this as fix released, even though that version of the charm isn't yet in the stable channel (we have a separate bug tracking that as well).
