Cloud provider region management

[roleyfoley]

Cloud providers are great in offering a global collection of data centre resources referred to as regions. However in reality or due to compliance most deployments are performed in a single region with some services deployed in other regions if required.

This ticket is to look into two concepts

• The ability to define a home region. This is the default region to deploy resources in and also defines where resources which are used at a global level are deployed ( S3 buckets for centralised logging etc)
• A list of secondary regions - A list of regions where resources can be deployed

Any region not specified as a home or secondary region and de-provisioned where possible and monitored for unexpected behaviour

@roleyfoley I'm not clear whether the intention is to set a HomeRegion : AltRegions : [ ] At the Tenant, Account, or Product level?

I assume "Any region not specified as a home or secondary region ... monitored for unexpected behaviour" will translate to raise a fatal error within hamlet when a component has a region not in the HomeRegion and AltRegions set
