Currently if you want to update a non-alias ref, you need to first check if it exists and use either `ostree refs --create` or `ostree reset` as appropriate. That's unnecessarily complicated and is much less convenient than the old `write-refs` builtin that simply called `ostree_repo_set_ref_immediate()` without any checks. Add a `--force` option to be used with `--create` that does not raise an error when the destination ref already exists. Closes: #1870 Approved by: jlebon

<para>

Lists all refs available on the host. If specified, PREFIX assigns the refspec prefix; default
|

prefix is null, which lists all refs. This command can also be used to create or delete refs.

without this option will strip the specified prefix

Enable interactions with refs using the combination of their

collection IDs and ref names. When listing refs, this changes

the output format to include collection IDs, and enables

listing remote mirrored refs.</para>

<para>When creating refs, the refspec value passed to the

<option>--create</option> option is treated as

<literal>COLLECTION-ID:REF-NAME</literal> and a mirrored ref

is created. (This is an abuse of the refspec syntax.)</para>

PREFIX are deleted.
