3.0.0

New features

• Support Flutter Web.
• Extract CookieManager into a separate package（No need for Flutter Web）.
• Provides HTTP/2.0 HttpClientAdapter.

Change List

• Options.cookies

• Options.connectionTimeout ；We should config connection timed out in BaseOptions. For keep-alive reasons, not every request requires a separate connection。

• Options.followRedirects、Options.maxRedirects、Response.redirects don't make sense in Flutter Web，because redirection can be automatically handled by browsers.

• FormData.from，use FormData.fromMap instead.

• Delete Formdata.asBytes()、Formdata.asBytesAsync() , use Formdata.readAsBytes() instead.

• Delete UploadFileInfo class， MultipartFile instead.

• The return type of Interceptor's callback changes from FutureOr<dynamic> to Future. The reason is here.

• The type of Response.headers changes from HttpHeaders to Headers, because HttpHeaders is in "dart:io" library which is not supported in Flutter Web.
