Added initial nginx services
- Proxy allows ingress traffic to be sent to another element in service mesh - Mirroring is also in the default configuration - Default configuration is to proxy to a clover-server and mirror to snort-ids - A location_path (URI in HTTP requests) can be reconfigured to restrict proxing; default to '/' - A proxy_path can be reconfigured to specify an alternate destination - A mirror path can be reconfigured to specify where traffic will be spanned - The default server_port (listen port) for the proxy is 9180 but can be reconfigured - The default server_name is http-proxy but can be reconfigured - Reconfiguration is done over GRPC with jinja2 template for nginx - Currently snort ids sends alerts to proxy with stub code in GRPC - Refactored the code to have a nginx base with subservices - Proxy, Load Balancer (lb), and Server can share code - mainly GRPC server - Nginx subservices have separate docker builds - Improved build scripts for CI - Render yaml manifests dynamically - Improve nginx_client for runtime modifications (but not really useful yet) Change-Id: Icbff6890021bcc8a8da4690c9261205d6e1ca43a Signed-off-by: Eddie Arrage <eddie.arrage@huawei.com>
