What is new in this version

• All parameters were moved to input file, and usage of deploy_aks_cluster.py - changed
• Microservices for test - installed automatically, by deploy_aks_cluster.py
• Readme file updated

What is planning for next versions of Cluster installation application

• Ingress configuration
• Add references to Microsoft documentation, to code, to better understanding and maintenence (?)
• More detailed readme file (?)
• Split Cluster installation application to several files (?), as it's long and contains 10 Classes. Although code is easy for understanding if using PyCharm (or similar IDE).
