Migrate Travis CI to Github Actions

Related to issue: #64

Actions now reach running the core tests but we get 404 from the relayer

@adzialocha found that docker-gen is having an issue with finding out the ip addresses of the created containers, so nginx-proxy doesn't know where to route the HTTP requests.

There seems to be an issue with a docker update affecting that ip-addresses are not properly added as upstream in nginx configuration
nginx-proxy/docker-gen#335
nginx-proxy/docker-gen#336

The above mentioned PRs are now merged / closed. However we still get the 404

FAIL test/token.test.js (7.399 s)
  ● Token › should check if safe has enough funds for token to be deployed

    RequestError: Request failed @ http://relay.circles.local/api/v3/safes/predict/ with error 404

      70 |       } else {

         |                 ^
      73 |         }

Was there a new version released / do we use it already?

[louilinn]

Should we update the version here?

Also the issue seems to remain when using a custom hostname (which i think we do here) according to comments in the PRs mentioned.

[adzialocha]

Should we update the version here?

Yes, super!

[adzialocha]

I think this is ready @louilinn and @llunaCreixent ! 🥳

I've updated docker-gen to 0.7.5 in circles-docker and removed tmate. Also all circles tests are passing now (locally): #63

To test this finally we need to merge the fixed tests with this CI update, so I suggest to bring both PRs into main and troubleshoot from there (when there is something missing).

[llunaCreixent]

Let's merge! great job!

Tests failing. See:

🥳 🥳 🥳 🥳 🥳

Woho! I changed the tests to --runInBand and it works, I really think we have a race-condition bug in the relayer (started a ticket here but will add more info soon: CirclesUBI/safe-relay-service#44). For now we keep that flag and move back to concurrently running tests when the bug was fixed (created an issue here: #75).

@louilinn if you could remove that PostgreSQL part (see feedback of @llunaCreixent), I'm happy to merge it (I have the admin rights to merge it even though the Travis CI is blocking) 🌴 🐧

[louilinn]

The PostgreSQL part is already gone :) I removed the travis file. I think we should squash all these commits when merging haha ^^
