Jun Wu ffd7707d3d changelog2: initial support for hybrid commits backend 
Summary:
Initial support for a backend using edeanpi.

Note this is just the first step. Most code paths are not updated to the
streaming API to get commit data, so they will error out with commit not found
errors.

Confirm that commit data can be fetched via edenapi:

  $ RUST_LOG=debug lhg dbsh --config experimental.lazy-commit-data=1
  In [1]: master= repo['master'].node()

  In [3]: cl.inner.getcommitrawtext(master) is None
  Out[3]: True

  In [4]: s=cl.inner.streamcommitrawtext(repo.nodes('master~10::master'))
  In [5]: it=iter(s)
