Added configurations for deploying Ghost blog on Kubernetes using MySQL and nginx-proxy. Included resource limits for ghost-blog-deployment and mysql-deployment.yaml, created ingress-service.yaml for nginx-proxy with https and http, and added ghost-blog-service.yaml and mysql-service.yaml for connecting the Ghost blog app to the MySQL server. Also added a namespace 'blog' for better organization of resources.
