As a:
Operator

I want:
A design document adding Managed Identity that has recently GA'd to Bedrock

So that:
I have clear test-driven strategy that modernizes Bedrock approach to supporting this new feature.

Describe the solution you'd like:

• Describe new Bedrock template environment to be added
• Incorporate modular terraform Cobalt test fixtures
• Add Unit Test design for support of new feature
• Add Integration Test design for support of new feature

Additional context:

• Subset of: MSI Unit Test for verfied validation within Bedrock #1197

Does this require updates to documentation?:
Yes
