Matthew Heon 997de2f8e9 Initial implementation of renaming containers
Basic theory: We remove the container, but *only from the DB*.
We leave it in c/storage, we leave the lock allocated, we leave
it running (if it is). Then we create an identical container with
an altered name, and add that back to the database. Theoretically
we now have a renamed container.

The advantage of this approach is that it doesn't just apply to
rename - we can use this to make *any* configuration change to a
container that does not alter its container ID.

Potential problems are numerous. This process is *THOROUGHLY*
non-atomic at present - if you `kill -9` Podman mid-rename things
will be in a bad place, for example. Also, we can't rename
containers that can't be removed normally - IE, containers with
dependencies (pod infra containers, for example).

The largest potential improvement will be to move the majority of
the work into the DB, with a `RecreateContainer()` method - that
will add atomicity, and let us remove the container without
worrying about depencies and similar issues.

Potential problems: long-running processes that edit the DB and
may have an older version of the configuration around. Most
notable example is `podman run --rm` - the removal command needed
to be manually edited to avoid this one. This begins to get at
the heart of me not wanting to do this in the first place...

This provides CLI and API implementations for frontend, but no
tunnel implementation. It will be added in a future release (just
held back for time now - we need this in 3.0 and are running low
on time).

This is honestly kind of horrifying, but I think it will work.

API Reference

The latest online documentation is automatically generated by two cooperating automation systems based on committed upstream source code. Firstly, the Cirrus-CI docs task builds pkg/api/swagger.yaml and uploads it to a public-facing location (Google Storage Bucket - an online service for storing unstructured data). Second, Read The Docs reacts to the github.com repository change, building the content for the libpod documentation site. This site includes for the API section, some javascript which consumes the uploaded swagger.yaml file directly from the Google Storage Bucket.

Since there are multiple systems and local cache is involved, it's possible that updates to documentation (especially the swagger/API docs) will lag by 10-or-so minutes. However, because the client (i.e. your web browser) is fetching content from multiple locations that do not share a common domain, accessing the API section may show a stack-trace similar to the following:

If reloading the page, or clearing your local cache does not fix the problem, it is likely caused by broken metadata needed to protect clients from cross-site-scripting style attacks. Please notify a maintainer so they may investigate how/why the swagger.yaml file's CORS-metadata is incorrect, or the file isn't accessible for some other reason.
