Add shared role managing event handler and event listener

[AnuradhaSK]

Purpose

$Subject

SharedRoleMgtHandler handles:

• On creating a role with application audience in the primary organization, created the shared roles in the organizations where the app is already shared
• On shared app creation in sub-organization

1. Create application audience roles defined in the parent application
2. Create organization audience roles if the shared app uses them and if the same organization role is not availble in the sub-org due to any other shared app

config to enable handler:

[[event_handler]]
name= "SharedRoleMgtHandler"
subscriptions =["POST_ADD_ROLE_V2_EVENT", "POST_SHARE_APPLICATION"]

SharedRoleMgtListener handles:

• On deleting a shared app(may be due to unsharing the app from given org/ delete the main app and due to that deleting shared app) deleting roles with organization audience in app-shared organizations if no other shared app use them

• On main application's role audience/role list update, track the change in preUpdate listerner and set into the threadlocal varibales. Add/ Delete roles from shared organizations

Part of: wso2/product-is#16363

How other Shared Role management happens:

1. On Rolename update of main role -> Rename shared roles names at role mgt DAO layer
2. On deletion of main role -> Handled shared role deletion in role mgt DAO layer
3. On changing permissions of the role in the parent organization -> Permission always assigned to the main role not to the shared role
4. On unsharing an application from a sub-organization -> Role mgt service level method to delete roles by app id
5. On deleting a shared B2B application in a parent organization with roles -> Role mgt service level method to delete roles by app id

Depends on:

• Add capability to associate v2 roles with applications wso2/carbon-identity-framework#5001
• Introduce Role-Management V2 wso2/carbon-identity-framework#4965
• New services to derive whether app is shared to a given org / get main app id #260
• Bump framework version
