Add `--also-remote` option to `verdi process dump`

[GeigerJ2]

Tries to open a connection to the remote Computer using the transport of the CalcJobNode, and gets the files and folders which were not originally dumped, either as they weren't part of the CalcJobNode's repository or retrieved.

Will add the tests once the implementation is somewhat stable.

Don't want to assign you officially for review, but still pinging @khsrali and @agoscinski here if you guys want to have a look 👀

Note: With PR #6584, it'll be possible to give a warning to the user about the total size of files that would be written to disk. We might eventually decide that it takes too long and one has to open too many transports, just to obtain the total file size to warn a user, so one could just issue a generic warning. The problem is that these files and directories are on the remote computer (if not deleted already), so one has to connect to get information about them.

Also, the returned file size will differ, as some of the files in the directory to which the RemoteData points to, will have already been retrieved. This can be checked for, based on e.g. retrieve_list, local_copy_list, etc.
