WIP: Implement LFS plugin storing large objects in local file system
This plugin uses JGit's FileLfsRepository class to provide a local file
system based large file storage.
Large files are stored under the plugin's data directory
$GERRIT_SITE/plugins/lfs-storage-fs
This change makes use of the corresponding WIP in JGit [1]. Therefore,
to test locally you need to build JGit from [1] locally. In order to
make this plugin usable you must build Gerrit from [2] with this version
of JGit. This can be done using the multi-cell buck build introduced
in [3]. Follow the instructions given in [3] to build gerrit including
jgit.
The plugin supports only in-tree buck build. To build it clone the
repository under .../plugins folder and then execute:
$ buck build plugins/lfs-storage-fs
