Release of nginx 1.17.8 and njs 0.3.8

Created release of the main branch nginx 1.17.8, within which the development of new features continues (in the parallel stable branch branch 1.16 only changes related to fixing critical bugs and vulnerabilities are made).

Key changes:

• In the directive grpc_pass support for using a variable in the parameter that defines the address has been added. If the address is specified as a domain name, the name is searched among the described server groups and if not found, it is resolved using the resolver;
• A bug in the processing of pipelined requests over SSL connections that could lead to a timeout has been fixed;
• Corrections have been made in the directive debug_points when using the HTTP/2 protocol.

Additionally, it can be noted release njs 0.3.8, a JavaScript language interpreter for the nginx web server. The njs interpreter implements ECMAScript standards and allows extending nginx capabilities for request handling using scripts in configuration. Scripts can be used in the configuration file to define advanced request handling logic, generate configurations, dynamically create responses, modify requests/responses, or quickly create stubs for troubleshooting web applications.
