BREAKING CHANGE: migrate to cloud run v2 resources

The Cloud Run Domain Mapping service is still in Pre-GA status after
more than 3 years. Google's documentation now suggest using load balancers
or Firebase Hosting as an alternative as there are limitations with the domain mapping service.
We are removing it from this module as it seems as though it will soon be deprecated.

BREAKING CHANGE: Remove Cloud Run Domain Mapping

This is initially planned to execute Django database migrations. However,
other use cases will exist I'm sure.

A map cannot have a key which depends on a resource which is unknown.
To resolve this issue I've refactored the map to have known key names.

Closes #38

As referencing Secret Manager secrets has moved to GA. See:

This works with Terraform v0.14.10; the data source is read before
the plan walk, so the existing deployed image can be determined.
However, it is suggested that future Terraform may combine the
refresh and plan walks which *may* result in a cyclic dependancy.

Do not remove the BETA stage as we are going to still use some BETA options like the mounting of secrets from GCP Secret Manager

Rather than ship our own monitoring module, make use of the
gcp-site-monitoring module. This effectively makes this module require
0.13 so a major version bump is required.

Closes #13

Allow an optional domain mapping to be configured for the webapp. If a
domain mapping is configured, appropriate DNS records are provided as
outputs.

Closes #2

This module manages a Cloud Run-hosted container. It takes care of making
sure the container is connected to a Cloud SQL instance and sets
environment variables on the application.
