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. [1] https://github.com/github/git-lfs/blob/master/docs/api/v1/http-v1-batch.md Change-Id: I7b93f3cf90f7344c90b1587e07927fdeb167097e Signed-off-by: David Pursehouse <david.pursehouse@gmail.com>
