#152

It's handy to expose the application getters and setters. That way we can work with the interface.

Merge pull request #151 from SimonRichardson/charm-actions

#151

Import/export charm actions, config, and lxd-profiles for a given charm. These represent the actual files that can be found in a charm. We require these configuration files, so that when we import a 3.6 or 4.0 model into a 4.0 controller, we can correctly infer all of the RI (referential integrity) when creating applications.

Merge pull request #147 from SimonRichardson/charm-metadata-manifest

#147

When migrating 3.6 to 4.0 we need to have the charm metadata and manifest upfront when importing an application. This is a requirement in order to keep RI (referential integrity) for the new SQL schema. The metadata and manifest are treated as an amorphous type, not as individual leaf types for every type of the metadata. This means when we want to rev the metadata it will be done at the root level (metadata and manifest only have a version).

Otherwise, the code is a replication of https://github.com/juju/juju/tree/main/internal/charm. Versioning of the charm will now impact model import/export. Changing the charm metadata is no longer free (probably never was, but always treated as such).
