Please setup a git-lfs server

We are going to have quite large example files within the datamodel git repo, and I expect that test data for the 1-D and 2-D pipelines may also be pretty large.

It is very convenient to handle this sort of thing with the git code/text, but git (and in particular github) doesn't handle large binary blobs very well. Fortunately the git-lfs ("large file system") extension does do this for us; unfortunately using github's service is expensive.

Please setup our own server to support git-lfs files within our git repos. The LSST project has done this, and can provide help as needed. If we decide to pay for github git-lfs, please provide a document discussing how we manage the data (e.g. ensuring that we don't use too much, or too much bandwidth).
