Refactor organization user sharing implementation and implement user sharing on sub-organization creation.

[sadilchamishka]

Purpose

$subject

Depends on

• Add organization user sharing related error messages wso2/identity-organization-management-core#86

Tested flows

• When create an organization, the authenticated user is shared to the organization with an organization role created. (This flow should be further improved to bind the user to an application role)
• The org creator should be able to switch to the organization. Need this - Involve user association for organization switching identity-oauth2-grant-organization-switch#21
• Another level of organization should be able to create. The associated user (The actual user) should be shared to that organization also.
• Invite an immediate parent user from the child organization.

Limitations

• Creating multiple levels of organizations while sharing the user to those organizations won't work for B2B enabled tenants.
  The carbon context lack the information of authenticated user's resident organization. The carbon context should be improved to have userResidentOrganization which can be set at the post authentication at valve level. Till that this workaround is done for make the feature work for super organization.
