Fix M1Session cache update after creating Policy Templates #85
Description
Description
When creating a new Policy Template, the local M1Session cache is not correctly updated. As a result, the methode policyTemplateIds form the M1Session return the old list until the cache-until timeout.
In rt_m1_client/session.py, the method policyTemplateCreate updates the internal details cache (ps['policyTemplates']), but it fails to append the new ID to the list of IDs (ps['provisioningsession']['policyTemplateIds']).
Solution
Add missing logic to append the new ID in policyTemplateCreate and logic to remove the old ID in policyTemplateDelete
