feat: Add etcd health and performance analysis commands

Add two new OpenShift plugin commands for etcd monitoring and diagnostics:

1. /openshift:etcd-check-health
   - Performs comprehensive health checks on etcd cluster
   - Validates member status, quorum, and connectivity
   - Reports disk space, database size, and fragmentation
   - Detects configuration issues and performance problems

2. /openshift:etcd-analyze-performance
   - Analyzes etcd performance metrics and latency
   - Examines disk I/O, compaction times, and snapshot performance
   - Monitors leader stability and detects frequent changes
   - Identifies slow operations and bottlenecks
   - Provides actionable recommendations for optimization

Both commands support OpenShift clusters with proper authentication
and provide detailed analysis with severity-based recommendations.
