Option for dev env to enable ssl for postgres

[fosterseth]

SUMMARY

PG_TLS=true make docker-compose

This will add some extra startup commands for the postgres container to generate a key and cert to use for postgres connections.

It will also mount in pgssl.conf which has ssl configuration.

This can be useful for debugging issues that only surface when using ssl postgres connections.

I'd also be okay with just writing up some docs on how to do this manually if we don't want to add more code to our bloated docker-compose.yml.j2 file
