toggle identity user updates

[shafiquech]

Description

This PR contains changes to add a flag to skip updates to User in Identity. After the recent Identity and Core Service Upgrade (2023.09-LTS) simultaneously updates to the Identity User often results in HTTP 409 Conflict this happens in the scenarios where there are more than 1 service agreements for a single user (i.e. one for Retail and other for Business). To make the change seamless for existing consumers the default value is set to true.
