Add Phoenix

[dantswain]

Probably the CI will fail right now because I haven't worked through any of the docker stuff. It builds and tests pass on my machine so far.

Done. Note - not a single one of those things was introduced by me. It was all from the templates that mix phoenix.new generates.

You'll have the following environment variables for connecting to the database. I can "rename" (OUR_ENV_VAR=$THEIR_ENV_VAR) these in the test script if desired.

SNAP_DB_PG_HOST
SNAP_DB_PG_PORT
SNAP_DB_PG_USER
SNAP_DB_PG_PASSWORD
SNAP_DB_PG_URL
SNAP_DB_PG_JDBC_URL

[dantswain]

We might want to change it to MEDERA_DB_URL or something that would make sense outside the context of the CI server.

The latest will probably still fail on the slack connection. See #fp chat for discussion on that.

[dantswain]

Hrm, it still acts like it doesn't know about SNAP_DB_PG_URL

[geowa4]

How about this as the run command? docker run --rm -e "SLACK_API_TOKEN=$SLACK_API_TOKEN" -e "MEDERA_DB_HOST=$SNAP_DB_PG_HOST" -e "MEDERA_DB_PORT=$SNAP_DB_PG_PORT" -e "MEDERA_DB_USER=$SNAP_DB_PG_USER" -e "MEDERA_DB_PASSWORD=$SNAP_DB_PG_PASSWORD" medera mix test

We need to make it so that the tests don't connect to slack. For the Db I think that's fine though we should be able to get away with just using the URL
