Enable CockroachDB For HA Goodness (WIP)

[bonedaddy]

• No real changes in this repo, instead the majority of the changes are within testenv and enable spinning up a single node cockroachdb cluster, instead of a postgresql node
• Enable a more secure db connection via client certificate auth

TODOs

• Add testing for secure db connection via certificates
  • This needs us to update the config package

Is this not longer a priority ?

Just asking because HA was the obvious thing i was looking for.

@gerardwebb This PR is technically tabled for now, however you can already use the database package in this repo with CockroachDB as it is wire compatible with postgres. The only difference however which this PR fixes, is that you can't do client-certificate authentication with any of the code in master or any releases.

Also you can technically implement HA out of this library, via logical replication and other stuff, but its annoying as fuck tosetup
