Merge master rest traffic to deploy-wakusim (#104)

* fix wakusim hostname

see https://github.com/status-im/infra-misc/pull/388

* chore: update docker compose command in README.md  (#99)

* Using shards, pubsubtopic is deprecated (#102)

* Move the rest-traffic logic inside waku-simulator (#103)

+# rest-traffic
+
+Test utility for [nwaku](https://github.com/waku-org/nwaku).
+Given the REST API endpoint, it injects traffic with a given message size at a given rate.
+
+See usage:
+```
+./python traffic.py ---help
+```
+
+Use with docker:
+```
+    build:
+      context: ./tools/rest-traffic
