Add docker-compose testnet

[mixmasala]

This adds Makefile targets to start and stop a local talek deployment using docker-compose and podman or docker. It provides a docker-compose.yml and writes a client configuration file for use with talekclient.

After manually editing talek.json to point at the frontend instance listening on :8080 I wasn't able to read/write data using talekclient. For example:

You should be able to replicate this by using the Makefile target testnet-start and testnet-cli, where the client configuration is written to /talek_net/talek.json inside the container

Is this a a point that's ready for a review?

Is this a a point that's ready for a review?

Yes please. Note that this has the fix from the other open PR (#110) merged to make the write-and-read integration test work.

Let me know if you're actually running travis somewhere and I could add it to .travis.yml too (or if you want to setup github CI to run it i could do that also/instead).

• I am not aware of a travis instance running somewhere
• happy to get github CI set up as well
