Add Entitlement operation in Web Service connector

@mkumariaas : Web service connector - Identity Security Cloud (ISC) / ISC Discussion and Questions - SailPoint Developer Community
I read in this post that for some reason on the add entitlement operation, IDN removed all fields that were not flagged as entitlements or were not the native Identity, even thought we have a before provisioning rule to add all the necessary infomration in the plan.
To solve this issue we created a before Operation rule to add those fields in the API body.
