Add support for Azure Cleanroom based CCF

[DomAyre]

TEMP: Targets the az-cleanroom branch until that's merged

Motivation

This allows us to test against a production-like mCCF replacement, and will allow us to validate it against a realistic use case for us

Changes

• Add an scripts/az-cleanroom-aci dir which installs the extension and brings up the network
• Provide a deployment name to conftest.py for deploying the network
• Handle up script having logs other than the resulting env
• Implement a way to remove all resources deployed by up.sh (maybe az cleanroom ccf network down?)
• Resolve trusting the service cert (temp using -k)
• Add runs of this to CI
