// Creates a Cedar policy and saves it in the specified policy store. You can
// create either a static policy or a policy linked to a policy template.
//   - To create a static policy, provide the Cedar policy text in the StaticPolicy
//     section of the PolicyDefinition .
//   - To create a policy that is dynamically linked to a policy template, specify
//     the policy template ID and the principal and resource to associate with this
//     policy in the templateLinked section of the PolicyDefinition . If the policy
//     template is ever updated, any policies linked to the policy template
//     automatically use the updated template.
//
// Creating a policy causes it to be validated against the schema in the policy
// store. If the policy doesn't pass validation, the operation fails and the policy
// isn't stored. Verified Permissions is eventually consistent (https://wikipedia.org/wiki/Eventual_consistency)
// . It can take a few seconds for a new or changed element to be propagate through
// the service and be visible in the results of other Verified Permissions
// operations.
