FrostFS Object Attributes are case sensitive key-value pairs. HTTP Gateway reads object attributes from HTTP headers of PUT request. To do this task correctly, gateway disables header normalization.

According to RFC7540#8.1.2

header field names MUST be converted to lowercase prior to their encoding in HTTP/2.

Any HTTP/2 proxy changes request headers, so gateway can't parse object attributes. Gateway also can't parse other useful headers like Authorization, but this is fixed in #121
