This will reduce the disk pressure [1] we have when a repository is large.SvnLoaderFromRemoteDump: Drop dump as soon as it's no longer required
[1] up to 3 copies ofThis will decrease the svn repository: 1 dump, 1 svn repository, and thedisk pressure currently existing when ingesting a svn diskrepository
copy we are creating along the ingestionout of a remote dump. We first fetch a dump, then mount a svn repository out of it, and
at last we ingest the repository and have a growing copy on disk [1].
So we are up to 3 copies which takes lots of disk space. With the following, we take
down the 1 unnecessary copy as soon as possible.
[1] implementation detail for speed.
