hs-test: proxy testing improvement

- new container topologies and suites for VPP proxy and Envoy proxy
- removed build docker image since it can't be used with CI cache
  builder, container builders are designed to be stateless, they
  only preserve build-cache, but not images

Type: test

+// The topology consists of 3 containers: curl (client), VPP (proxy), nginx (target HTTP server).
+// VPP has 2 tap interfaces configured, one for client network and second for server/target network.
