Summary:
There are a few separate steps during blobimport. One of them is inserting the
blobs and another is inserting the changesets. That worked fine if RevlogRepo was
static. However if RevlogRepo has changed between first and second step we
could've inserted blobs for N commits, but insert (N + X) changesets into
changesets table. That means that a few commits would have no blobs at all.
This diff fixes it by fixing the changesets that we want to blobimport
beforehand.

Summary:
Currently, any sort of `Bytes` can be stored in the blobstore. That
caused me to make several mistakes while writing the code to store bonsai
changesets, because I'd just end up storing the wrong set of `Bytes`.
Introduce stronger typing so that only types that explicitly implement
`BlobStorable` can be stored in the blobstore.
Currently, these sorts of blobs can be stored in the blob store:
* `ChangesetBlob` and `ContentBlob` in `mononoke-types` (these are Thrift-serialized structures)
* The envelope `RawNodeBlob` and `RawCSBlob` types in `blobrepo`, once converted to `EnvelopeBlob` instances
* `HgBlob`, which contains revlog data (manifests or files) exactly as serialized by Mercurial

Summary:
The new_blobimport as opposed to the old one do two things differently:
1. It uses a better structured API of RevlogRepo. The old one reads the Revlogs directly and does not verify if the data it has read is correct or it does not let us fix it into canonical form easily (once we have a canonical form different from Revlog's).
2. It uses BlobRepo's Commit API instead of writing directly to storage. This ensures consistency in our code and let's us leverage the validation that is incorporated in Commit API.

Summary:
Provide an API to ask BlobRepo to create changesets for you from
pieces that you either have to hand, or have created via upload_entry().
Parallelism is maintained in as far as possible - if you commit N changesets,
they should all upload blobs in parallel, but the final completion future
depends on the parents, so that completion order can be maintained.
The ultimate goal of this API is to ensure that only valid commits are added to the `BlobRepo` - this means that, once the future returned by `create_changeset` resolves, you have a repo with commits and blobs in place. Until then, all the pieces can be uploaded, but are not guaranteed to be accessible to clients.
Still TODO is teaching this to use the complete changesets infra so that we
simply know which changesets are fully uploaded.
