Introduce timeout and delay realization parameters

Realization data source can now be fine-tuned with two new params:
* delay defines wait time befor realization polling begins
* timeout defines the timeout for realization polling

 ## Argument Reference
 
 * `path` - (Required) The policy path of the resource.
-
 * `entity_type` - (Optional) The entity type of realized resource. If not set, on of the realized resources of the policy resource will be retrieved.
-
 * `site_path` - (Optional) The path of the site which the resource belongs to, this configuration is required for global manager only. `path` field of the existing `nsxt_policy_site` can be used here.
+* `delay` - (Optional) Delay (in seconds) before realization polling is started. Default is set to 1.
+* `timeout` - (Optional) Timeout (in seconds) for realization polling. Default is set to 1200.
 
 ## Attributes Reference
 
 In addition to arguments listed above, the following attributes are exported:
 
 * `state` - The realization state of the resource: "REALIZED", "UNKNOWN", "UNREALIZED" or "ERROR".
-
 * `realized_id` - The id of the realized object.
