Persona: This is for Centreon Admin on one side but mainly for Centreon users
Problem to solve: As an Centreon admin, I want to be able to share new custom views or modify existing ones and make those changes available to selected users. Those users would have no further action to make to benefit from these changes.
Expected outcome: Ease custom views usage for Admin and non Admin users
Potential solution: Revisit the custom view share process to allow immediate application for non Admin users.
Based on GitHub proposition
