By default, it will generate hostname using the aws region passed to the
constructor.
This will allow for easier testing, since you can just spin up a local
minio (or other s3-compatible storage service) instance and point the
application at that for the storage mechanism.
It will also allow for storing lfs objects on-prem.

The tag is formed inconsistently to tags in the rest of the JGit code
base (i.e. "4.10.0" with a trailing ".0" where all the others don't).
However since this class is not in the public API, the @since tag is
not necessary and can just be removed.

Format @Nullable on return value as method annotation
For example, instead of using
public @Nullable String getMyFavoriteString() { ... }
use
@Nullable
public String getMyFavoriteString() { ... }
This makes the style more consistent (the existing JGit code base
tends to lean toward the second style) and makes the source code
better reflect how the annotation is parsed, as a METHOD annotation.
Longer term, we should switch to a TYPE_USE annotation and switch to
the first style.
Noticed using a style checker that follows

If yes we cannot set response status or send an error message, last
resort is to close the outputstream.
If the response wasn't yet committed first reset the response before

UnsupportedEncodingException is not thrown when the StandardCharset

Because the encoding names are no longer hard-coded strings, also

Don't rely on default locale when using toUpperCase() and toLowerCase()
Otherwise these methods may produce unexpected results if used for
strings that are intended to be interpreted locale independently.
Examples are programming language identifiers, protocol keys, and HTML

"t\u0131tle", where '\u0131' is the LATIN SMALL LETTER DOTLESS I

Add support for refusing LFS request due to invalid authorization
Add a new exception type that server implementations can throw when a
client attempts to make an unauthorized LFS operation, which will result
in HTTP 401 Unauthorized being returned to the client.
An example of this is a Gerrit server that rejects a request to perform
an LFS operation on a ref that is not visible to the caller.
As defined in the LFS spec [1] the request may include authentication,
and per RFC 2616 [2], "401 response indicates that authorization has been
refused for those credentials".

LfsProtocolServlet: Add support for rate limit and bandwidth limit errors
The git-lfs specification [1] describes the following optional status codes
that may be returned:
429 - The user has hit a rate limit with the server. Though the API does
not specify any rate limits, implementors are encouraged to set some
for availability reasons.
509 - Returned if the bandwidth limit for the user or repository has been
exceeded. The API does not specify any bandwidth limit, but implementors
may track usage.
Add two new exception classes to represent these cases. Implementations may
throw these from #getLargeFileRepository(), causing the corresponding HTTP
status codes to be returned to the client.
