feat: moving to cs 4.6 and explicit sub

[giacomoch]

Succesful build: https://hyc-cip-jenkins.swg-devops.com/job/Automation/job/global_catalog_automation/372

• CS is now installed at the 4.6.1 level:

• CS subscription is now explicit, and not relying on the AA operator to install it
• Cp4I operator patched so it works with CS 4.6.x
