[Corestack] Configure Azure VMs for high availability

The platform identifies Azure Virtual Machines (VMs) that are not configured for high availability and recommends implementing availability zones, availability sets, or virtual machine scale sets. Failure to configure high availability leaves critical workloads vulnerable to downtime from hardware failures, maintenance events, or other disruptions, potentially impacting business continuity.

Recommendation Impact Across KPIs

KPI	Impact	Calculated?
Reliability:	Reduces potential downtime through redundancy and fault tolerance	✅
Security Compliance:	No direct security impact	❌
Economic:	No direct economic impact calculated	❌
User Experience:	No direct user experience impact calculated	❌
Environment:	No direct environmental impact calculated	❌

Score Calculation

1. Data Ingestion

VM Instance Names
Current Availability Configuration
Zone/Region Distribution
Scale Set Membership

2. Data Enrichment

Mapping to Availability Requirements
Suitable HA Configuration Options
Potential Downtime Risk Assessment

3. Health Score

Calculate the Reliability score based on potential downtime minutes
Score multiplier increases based on time since recommendation was loaded (0.01 per day)
