rustic Allow to merge snapshots

rustic backup only accepts one path to being backup'ed.

Changing this directly is tough as the ignore crate is used which also only support one path. A workaround is to specify only one path and use suitable glob files.

Another workaround would be to allow merging snapshots, see https://github.com/restic/restic/issues/3792. This would also allow to easily solve the "multiple paths" issues as this could be done by auto-merging multiple generated snapshots within one rustic backup run.

After #177 is merged, multiple sources are possible. Rustic only creates multiple snapshots in that case. So this issue now is about merging multiple snapshots into a single one.

I'd propose to add a backup --merge option which creates one single snapshot in the case of multiple sources.

See #289 for an example how to use globs to filter a backup source such that it results in the same snapshot as multiple sources (i.e. same snapshot content, only the "paths" field in the snapshot file is different) .

Actually multiple sources are already WIP in #458 , so I'd like to change the scope of this issue to just add an merge command which is able to merge snapshots. This is also WIP, see #411
