def aws_sign_request(http_request, signing_config):
"""
Perform AWS HTTP request signing.
The :class:`awscrt.http.HttpRequest` is transformed asynchronously,
according to the :class:`AwsSigningConfig`.
When signing:
1. It is good practice to use a new config for each signature,
or the date might get too old.
2. Do not add the following headers to requests before signing, they may be added by the signer:
x-amz-content-sha256,
X-Amz-Date,
Authorization
3. Do not add the following query params to requests before signing, they may be added by the signer:
X-Amz-Signature,
X-Amz-Date,
X-Amz-Credential,
X-Amz-Algorithm,
X-Amz-SignedHeaders
Args:
http_request (awscrt.http.HttpRequest): The HTTP request to sign.
signing_config (AwsSigningConfig): Configuration for signing.
Returns:
concurrent.futures.Future: A Future whose result will be the signed
:class:`awscrt.http.HttpRequest`. The future will contain an exception
if the signing process fails.
