Nightly build that destroys and applies what's in the repo

[glennmusa]

Description

We could use a nightly build to know if any changes in source have occurred that would effect the ability to deploy missionlz.

The assumption is that if this build is broken, the product is in an non-working state and the team swarms to resolve the problem as quickly as feasible.

Will look to where this can be done from internal tooling.

This may depend on finishing #89.

Acceptance Criteria

• Assumes mlz_tf_setup has been run for the pipeline
• The build uses some configurable subscription ID(s) to deploy into
• The build uses the same container developers use
• The build runs terraform apply for the base Hub + Spoke
• The build runs terraform destroy for the base Hub + Spoke
• The build runs the Bicep deployment with defaults
