Summary:
We'd like to enable `lfs.url` on hg servers to make blob verification work
without downloading actual blobs. Previously, the LFS local blob store is
always backed by the local filesystem. D6699099 added a simple in-memory store
for another purpose. That in-memory local store fits the
"avoid downloading to disk" purpose. So let's add a config option to use it.
